1 - Introduction

    As a general note, I'd like to explain that all references to 
    resources available on the network are given in the form of a URL. 
    See appendix A for an explanation if you have problems. 

    Additionally, the pointers to resources at FTP sites are almost 
    never the sole place to obtain information. If you have trouble 
    finding a file at a particular site, use archie to locate it at a 
    different place on the net. See appendix E for more information. 

    The most recent version of this FAQ can be obtained from:

  1.1 Purpose

      Most of the questions posed on comp.emulators.misc seem to be of 
      the form, "is there a XXX emulator for XXX? Where can I find 
      it?" This FAQ cannot pretend to answer every possible 
      permutation of this question, but, hopefully, it will be 
      possible to knock out the most common ones. 

      There is also quite a bit of information which could be useful 
      to developers (pointers to specifiations, etc) contained in this 

  1.2 What is not included

      This document excludes topics that are not covered by the 
      comp.emulators.misc charter (see appendix F), such as sound card 
      emulation (use, math 
      co-processor emulation (use, and 
      the X windowing system (use For the record, 
      there is no such thing as an X "emulator;" X is a standard. You 
      IMPLEMENT it on a platform, not EMULATE it. 

      Furthermore, this document specifically excludes those machines 
      for which an emulation FAQ has already been written. You may 
      wish to check the FAQ archives listed in appendix H. 

      Specific FAQs which should be referenced instead of this 
      document follow.

  1.3 General Resources

    1.3.1 Tenabis Emulator Classes

        Sebastien Brochet <> has put together 
        some interesting C++ classes that may prove interesting and 
        useful to potential emulator developers. He also has a small 
        virtual machine ("Tiny Emulator") and an assembler for that 
        machine ("TinyAsm") available from the same page. Sebastien is 
        using these classes to implement an Atari ST emulator. 

2 - Processor Emulation

    A comprehensive listing of chip specifications is available for 
    those people wishing to create emulators. It is available at the 
    following sites (and several other mirrors, listed at each site):

  2.1 6502/6507/6510

    2.1.1 6502 Emulation Package (Source)

        The source for the 6502 emulator which Marat Fayzullin 
        <> has written and based a few emulators on. 
        He has given permission for this code to be used in 
        non-commercial non-profit programs, so long as proper credit 
        is given. 



  2.2 6800

    2.2.1 68em [MS-DOS]

        6800 emulator for DOS; includes a realtime O/S. 

        I have very little information about this program, other than 
        a report that the ROL direct instruction does not rotate the 
        carry flag into the low bit of the operand properly (although 
        ROLA does). If anyone can find a version of 68em dated after 
        1991-Jun-15, a pointer to that may be helpful. 


  2.3 6809

      Some information on the 6809 can be found on :

    2.3.1 usim (Portable)

        C++ class implementation of a 6809. Includes a derived class 
        which shows processor stats in an X window. It has been tested 
        under Linux. Written by Ray Bellis <>. 


  2.4 6811

    2.4.1 M68HC11 emulator

        M6811 emulator and debugger; it is in its final stages of 
        development. The processor emulation provides emulation of 
        devices, provides an execution history, allows step debugging, 
        and has several styles of breakpoints for debugging. See the 
        homepage for more information.

  2.5 680x0

    2.5.1 68000 Assembler/Simulator [MS-DOS, VMS]

        A 68000 simulator with a cross assembler. Includes source. No 
        information is available on where to find this simulator. 

        Written by Marwan Shaban <> 

    2.5.2 68k-simulator [Unix & X]

        MC-68000 Simulator for X-Windows 



    2.5.3 BSVC [Unix & X, Windows 95]

        Microprocessor Simulator (Motorola 68000, Hector 1600); it is 
        copyrighted, but may be freely distributed. The Unix version 
        requires Tk/Tcl to compile. The Windows 95 version does not 
        include support for the M68681 Dual UART. Written by Bradford 
        W. Mott <> 



    2.5.4 EMU68 [Unix, MS-DOS]

        M68000 emulator for MS-DOS and UNIX. This emulator was 
        developed as part of a MS thesis. It is written entirely in 
        C++, and the source code is available. On a '486-33, it runs 
        about 1/50th as fast as an MVME101 (an embedded procssor 
        board). Two separate sets of source are available -- one for 
        MS-DOS (which is known to work with the Borland C++ 
        compilers), and one for Unix. 

        The emulator does not support the following opcodes: ABCD, 
        CHK, MOVEP, NBCD, SBCD, and TAS. 

        The developer has offered to supply development documents to 
        anyone who needs to modify the source code.

  2.6 68HC11

    2.6.1 M6811 [MS-DOS]

        Written as a final project for university. Includes a debugger 
        and benchmark program. See the homepage for more information. 
        Written by Bambang Sutanto <>. 


    2.6.2 Motorola 68HC11 uController simulator [MS-DOS]


  2.7 80x86

    2.7.1 Bochs [Unix & X]

        This is an 80x86 emulator which runs on most Unix platforms 
        under X. It emulates the CPU, BIOS and I/O environment of an 
        IBM AT compatible PC. 

        Currently, the program is in Alpha, but it has an impressive 
        list of accomplishments. It can handle 386 opcodes, and runs 
        DOS 5.0 & 6.22 and Windows 3.1 (in standard mode). Hardware 
        support includes Hercules graphics, PIC, timers, 
        1.44M/1.2M/760K floppies, and AT keyboard. Plans are to 
        emulate VGA graphics. 

        Currently, Bochs does not support networking, numerics 
        coprocessor, or mouse emulation. Tasking & paging are missing 
        in the CPU support, but paging is currently being implemented. 

        For embedded systems developers, PC BIOS developers, O/S 
        developers, CPU vendors, etc, Bochs supports the use of an 
        external BIOS, and provides a compile time option for linking 
        with an external CPU simulation environment. 

        There is also a mailing list for this emulator:

3 - Operating System Emulation

  3.1 AES

    3.1.1 oAESis

        A free replacement for the AES that runs on Atari or 
        compatible computers. It aims to have all the features of 
        MultiTOS. It requires MiNT to run. By Christer Gustavsson 


  3.2 Amiga OS

      While no functioning Amiga OS emulators currently exist, there 
      is at least one group of citizens attempting to write one. See 
      also section 4.4.2. 

    3.2.1 AmigOS (work in progress)

        This is a voluntary project to port an Amiga OS compatible 
        operating system to other platforms. As of yet, no programs 
        have been produced, and the pages have not changed in quite a 
        while. What started out as a fairly promising project appears 
        to have stalled or died. For more information, check out their 


  3.3 CP/M

    3.3.1 22nice [MS-DOS]

        22NICE is an emulator of 8-bit CP/M 2.2 systems using 8080, 
        8085 or Z-80 processors; it runs under MS-DOS. It includes 
        terminal emulation for several common terminal types, 
        8080-only Z-80 only, or "auto detect" processor support. It 
        will use a NEC V20/V30 chip if one is available. 22NICE 
        Supports CP/M user number-to-DOS subdirectory mapping and 
        custom keyboard maps. A facility to trap and handle 8-bit I/O 
        references is also provided to allow emulation of 8-bit 
        hardware not present on a PC. 


    3.3.2 ame86 [MS-DOS]

        CP/M-86 emulator for MS-DOS system. 


    3.3.3 CP/M Emulator [MacOS]

    3.3.11 z80mu [MS-DOS]

        CP/M (Z80 processor) emulator for MS-DOS. Shareware; 
        registration is US$150 per user. This is purportedly a very 
        accurate and high-quality emulation. Written by Joan Riff. 


    3.3.12 Zsim [MS-DOS]

        Z80 CP/M emulator for MS-DOS. Includes source code (80x86 
        assembly and Modula-2), but you must register (US$50) before 
        you can decode the source (actually, it doesn't appear to be 
        scrambled at all, although the documentation claims it is). 
        This emulator is free for personal use. Requires an 80286 or 
        higher. Written by Juergen G. Weber 


  3.4 Flex

    3.4.1 6809 Flex Emulator [Windows 95, AmigaOS]

        This package is a full 6809 emulator which runs the Flex 
        operating system. It outruns the original setup on a P60.

    3.5.1 Bochs [Unix & X]

        See section 2.7.1. 

    3.5.2 CrossPC [Amiga]

        MS-DOS emulation for the Amiga. CrossPC was produced by 
        Consultron. It was formerly bundled with CrossDOS, a utility 
        to read, write and format MS-DOS media on an Amiga. The last 
        version of CrossPC was with CrossDOS 5; CrossDOS 6 no longer 
        includes CrossPC, which has been discontinued. CrossPC 
        emulated a PC-XT with CGA graphics.

    3.5.3 DOSEMU [Linux]

        Emulates DOS under Linux, FreeBSD, and NetBSD. Suposedly, this 
        is a farily robust emulation. It is rumored that this will 
        soon be capable of running Windows 3.1. 


    3.5.4 DOS Merge [80x86 Unix]

        DOS Merge is a text-mode MS-DOS emulator produced by Platinum 
        Technology. The November 1995 issue of BYTE reports that 
        Platinum (Locus, at the time) licensed source code from 
        Microsoft to produce this emulator, just as Insgnia Solutions 
        did for SoftPC and SoftWindows. 


    3.5.5 FreeDOS [80x86]

        Not really an emulation, but more of a replacement for MS-DOS 
        released under the GNU general licence. The concept is that 
        FreeDOS will provide DOS support after MicroSoft discards the 
        operating system. Of course, since it's a GNU licence, all 
        source code is freely available. 


    3.5.6 IBeM [Amiga]

        MS-DOS emulation for the Amiga. 


    3.5.7 MDOS [Mach 3]

        Emulates DOS programs under Mach 3 as if they were running on 
        a 80286. Can run MS-Windows 3.0, so it can also be used as a 
        Windows emulator. 

    3.5.8 Merge [Solaris]

        Provides MS-DOS emulation under Solaris x86. More information 
        is available from the homepage. For Sparc users, see SunPC 
        (section 6.4.11). Produced by Sun Microsystems. 


    3.5.9 PC-Ditto [Atari ST]

        This is a software based MS-DOS emulator for the Atari ST. 
        Version 3.96 is capable of emulating an 8086 with full CGA and 
        MDA support. It can run Turbo Pascal 6, MS-DOS 5, 10Rogue, and 
        Indy 500, among other programs. Unfortunately, it rates about 
        1 MHz (less than 1/4th the speed of the original PC machines), 
        so it's not useful for any serious applications. 

    3.5.10 PC-Task [Amiga]

        Version 4.0, now available, runs 80486 MS-DOS/Windows programs 
        on Amiga machines.

    3.5.13 SoftPC [NeXTStep, MacOS, Atari TT, Atari Falcon]

        Runs MS-DOS programs under MacOS and NeXTStep. The newer 
        NeXTStep product requires 80x86 based machines; it will not 
        work on 680x0 based NeXTStep machines (although older versions 
        did work on the 680x0 machines). Produced by Insigna 

        It is probable that Insigina has included the same emulation 
        that they use for SoftPC in their SoftWindows product. See 
        section 3.6.6 for details on SoftWindows. 

        The Atari ST/Falcon version was never officially released, but 
        an alpha version was (illegally) included on a German 
        shareware CD at some point. It runs about as fast as an 
        original XT on the Falcon, and about twice as fast as that on 
        a TT.

    3.6.8 Wabi [Solaris, Linux]

        Runs MS-Windows 3.1 executables under Solaris. Supports OLE. 
        Produced by Sun. Wabi is a Trademark of Sun Microsystems. Wabi 
        cannot run MS-DOS applications; however, SunPC (Sparc) and 
        Merge (80x86) will run under Wabi. See section 6.4.11 for 
        information on SunPC and section 3.5.8 for information on 

        Wabi operates by translating MS-Windows API calls into 
        corresponding X calls, providing faster translation than full 
        emulation would. 

        Sun is planning support for 32-bit (Win32s, Windows 95, 
        Windows NT) applications in future releases, but they have not 
        announced an expected date for such support. 

        Sun has also announced plans for a version of Wabi that allows 
        the installation of Windows with the Japanese character set. 
        Support is planned for French, Italian, German, Spanish and 
        Swedish versions. 

        Caldera (producers of Caldera Desktop, a commercial 
        distribution of Linux) has released Wabi for Linux. For more 
        information, see the Caldera homepage. Suggested retail price 
        is US$199.

    3.7.1 Equal Application Adapter [Solairs, Irix, HP-UX]

        Emulates a 680x0 Macintosh under Unix; this emulator maps 
        MacOS system calls to equivalent Motif calls, much like Wabi 
        does for MS-Windows (see section 3.6.8). Produced by Quorum 

    3.7.2 Executor [MS-DOS, Linux, NeXTStep]

        Executor is a Macintosh emulator which works with MS-DOS, 
        Linux, and NeXTstep. It was developed completely independant 
        of the Macintosh ROMs, so you don't have to worry about 
        hunting down ROM images to use it. Limited (incomplete) System 
        7 support is available in versions 1.99p and later. 

        Furthermore, in versions 1.99p9 and later, limited sound 
        support is available for the MS-DOS and Linux versions. The 
        Linux versions run under X, although an experimental SVGALib 
        version is available. There are a.out and elf versions of the 
        Linux binaries. 

        Executor runs at an unbeleivably fast speed, thanks to dynamic 
        recompilation of 680x0 machine code into native 80x86 machine 
        code for certain segments of code. More information on this 
        technique is available on the FTP sites listed below; retreive 
        "SynPaper" or "SynPaper.tex." 

        The demonstration program listed below has full functionality, 
        but stops running after 10 minutes.

        Emulation of Mac System 6 on a 680x0. It does no mapping of 
        graphics calls, and requires the user to source his own copy 
        of system 6.0.7.

    3.7.4 MAE/MAS [Solaris 2.3, HP-UX 9.01, PowerOpen Unix]

        MAE (Macintosh Application Environment) is produced by Apple; 
        it runs Mac OS executables on Sparcs with Solaris 2.3 or later 
        and HP 9000 Series 700 machines with HP-UX 9.01 or later. 

        MAS (Macintosh Application Services) is also produced by 
        Apple; it seems to be very similar to MAE, but runs on RS/6000 
        machines under PowerOpen Unix. 

        This program uses a dynamic recompiler to speed up emulation.

    3.8.1 MagiC-Mac [Macintosh]

        Magic for the Mac. This is a commercial product produced by 
        Application Systems Heidelberg. Since it is written in native 
        680x0 code, it typically runs faster than an ST with TOS. A 
        PowerPC version is rumored to have just recently been 
        released; its performance is described as being 10% faster 
        than a TT.

    3.9.1 FreePort Express [DEC Alpha]

        FreePort Express does translation of binaries from SunOS 4.1.x 
        to DEC UNIX 3.0 or later. It is a free program. 

        Freeport requires the binaries to be converted to be 
        non-privledged, user mode a.out files. It will not work with 
        file or filesystem formats which are not present (or are 
        different) under Digital UNIX, code which uses SunView, or 
        driver code. 

        After conversion, the same code runs about the same speed (or 
        faster) on an AlphaStation 400 4/233 as it does on a SPARC 


4 - Machine Emulation

    In many cases, especially the eariler home computers, the 
    operating system was so closely tied to the hardware that it is 
    virtually impossible to emulate one without emulating the other. 
    This section contains entries for these types of emulators. 

  4.1 ABC80

      The ABC80 is an early-'80's Swedish home computer based on the 
      Z80; it was more or less on par with the other 8-bit home 
      computers of its time. The ABC80 has 16k RAM and 16k ROM. It was 
      manufactured by Luxor (who generally are in the business of 
      consumer electronics, like television sets, etc.). 

      Judging from the responses I get when making queries, it was a 
      fantastically popular computer (like the BBC was in Brittian). 

    4.1.1 ABC80 [MS-DOS]

        ABC80 Emulator for PCs. Written by Erik Isaksson 
        <>. Part of the documentation is in 
        Swedish; enough is in English that you don't need to know 
        Swedish to use it. 


  4.2 Acorn Atom

    4.2.1 Acorn Atom Emulator [Unix & X]

        This emulator is available under the Gnu Public License. See 
        the homepage for the current status of this emulator. Under 
        development by Frans F.J. Faase <>. 


  4.3 Altair

      The Altair was one of the first kit computers that could be 
      ordered out of electronics enthusiast's journals; it was first 
      released in 1975. It was a small, rectangular box with a couple 
      dozen switches on it. You would use these to toggle in your 
      program and execute it. The output was 20 LEDs which indicated 
      various flags and one 8-bit value. 

    4.3.1 Altair 8800 Emulator [MS-Windows]

        Altair 8800 emulator for MS-Windows. Has nifty graphics of the 
        original machine. Also performs IMSAI emulation. Written by 
        Claus Giloi. 


  4.4 Amiga

      For a long time, there has been an ongoing argument about 
      whether an Amiga emulator would be possible; in a decisive blow 
      to those claiming it is impossible, a usable (and even zippy, 
      under certain circumstances) emulator has been developed and 
      released; see below for details. Still, from the days when such 
      an emulator was beleived impossible, there are a few odd hoaxes 
      and rumors. 

      Due to the nature of the Amiga floppy drive hardware, it is 
      impossible to read Amiga floppies in an IBM-PC floppy drive 
      without heavily modifying the hardware; the Amiga can read and 
      write in IBM format, though. In fact, as far as common knowledge 
      extends, it is absolutely impossible to read Amiga disks in 
      anything but a genuine Amiga. 

      Another chapter in the long Amiga saga: VIScorp has purchased 
      Amiga Technologies, GmbH from Escom. For those keeping track, 
      this makes the fourth holding company for the Amiga. More 
      information is available from both websites:

      This has very few ramifications for the emulator; the largest 
      one is that VIScorp has made it extraordinarily clear that they 
      intend to pursue blatant copyright violations, such as kickstart 
      ROM distribution. In an official memo on their website, they 

      "...[W]e have recently become aware that versions of the Amiga 
       System ROMs are being reproduced and distributed without proper 
       licensing. This is a violation of international copyright law, 
       and VIScorp will prosecute offenders to the full extent of the 

    4.4.1 (Hoax)

        A program which purports to be an Amiga emulator for MS-DOS 
        machines has existed for a while. All it does is display the 
        Kickstart 1.2 startup image and hang your machine. (It wasn't 
        designed to do anything else. It's someone's sick idea of a 
        joke.) Note that this program has turned up in a number of 
        shareware CD collections that are otherwise reputable -- it's 
        still the same fake. 

    4.4.2 UAE [Unix & X, Macintosh, MS-DOS, NeXTstep, BeBox, AmigaOS]

        UAE (Un*x Amiga Emulator) is a developing emualtor of the 
        Amiga 500/2000. 

        To use UAE, you need Unix and X (or Linux SVGAlib), a C 
        compiler, and a Kickstart ROM image (1.3, 2.0, and 3.0 all 
        work). The current version includes emulation of HAM graphics; 
        sprites; the Blitter and Copper chips; timers; disk drive 
        support; interlaced graphics mode emulation; parallel port 
        emulation (requires the WB3.0 PostScript driver); support for 
        French, Italian, and Swedish keyboards; and joystick support 
        (Linux only). Caveats include: Sprite collisions are not yet 
        implemented; the blitter chip isn't emulated at full speed; 
        some sound problems persist. 

        As of version 0.6.4, UAE is moving towards a recompiling 
        processor, which should improve performance greatly. 

        A Mac version is available; it includes binaries for the 680x0 
        Macs and PowerPC Macs. This port was done by Ernesto Corvi 
        <>. Any Mac specific questions should 
        be directed to him. 

        A MS-DOS version has been produced; the port is by Gustavo 
        Goedert <GGOEDERT@MUSIC.PUCRS.BR>. Any questions about the 
        MS-DOS port should be addressed to him. 

        A BeBox port has been done by Christian Bauer 

        The NeXTStep port is maintained by Ian Stephenson 

        Believe it or not, UAE has been ported to the Amiga. Olaf 
        'Olsen' Barthel <> maintains that port. 

        A Linux (elf) binary is available from the homepage.

        transdisk program included with UAE; it requires a null-modem 
        cable, and is available from:

    4.5.9 STonX [Unix & X, MS-DOS, MS-Windows]

        This is an Atari ST emulator that runs under Unix with X. It 
        requires an image of TOS to run (look for a program called 
        "dumptos.ttp" which should be on all sites with STonX). 

        Version 0.6 has been released. It is available from the 
        homepage below in source and Linux binary forms. New features 
        include serial and parallel port support, a Unix filesystem 
        interface, and sound support on many systems. Version 0.6 is 
        60% to 80% faster than 0.5.X on most systems. STonX will also 
        now boot TOS 1.0 - 2.06 (although 1.4 or higher is needed to 
        use the Unix filesystem interface). Developed by Marinos 
        Yannikos <>.

        help speed. It allows direct filesystem access to floppies, 
        CD-ROMs, and hard drives. Requires an 80486-66 or faster; a 
        Pentium-100 provides emulation speed on par with a TT-030.

  4.6 BBC

      The BBC appears to be a tremendously popular computer in Europe. 
      Unfortunately, most Americans have no idea what one is -- 
      despite the fact that a US version (with modifications for FCC 
      approval) was produced and sold. So, in addition to the normal 
      entries for emulators, I've included a not-so-brief description 
      of what these little machines are. Also, there exists a mailing 
      list for BBC emulators, but I get the distinct impression that 
      it is primarily for developers. For information, send mail to

      There seem to be an inordinate number of posts requesting BBC 
      ROMs on the group. To reiterate: it is illegal in almost all 
      countries to use ROM images which you do not own. However, it's 
      not completely clear whether you may use images of ROMs you own 
      but obtain from a second source (U.S. Residents, see appendix

      From Paul Boddie <>: 

      "Apparently, according to folklore :-) the BBC were working with 
       the people who made the NewBrain computer, to design the BBC 
       microcomputer. However, they were persuaded to throw the 
       competition open to at least Acorn. There are various tales of 
       how Acorn, with the design of the Proton, but with no idea of 
       whether it would work, built the first BBC within three days or 
       so. It worked well enough to persuade the BBC (corporation that 
       is!) to adopt it as the BBC computer. 

      "The closest predecessor was the Atom, and various other 
       machines were made as 'spin-offs' including the Electron, BBC 
       B+, Master series, Acorn Business Computer (never released as 
       such), and Acorn Cambridge Workstation. (Forgive me if I have 
       missed one out!) 

      "Its key features were: 32K RAM (model B - the model A had 16K 
       expandible to 32K model B status), BBC BASIC 2 (early models 
       had BBC BASIC 1), 6502 series processor, analogue joystick 
       port, parallel printer port, Econet (optional?), Tube (a second 
       processor interface), disc interface, graphics modes (640 * 256 
       * 2 colours, 320 * 256 * 4, 160 * 256 * 16 etc.), plug in 
       language and 'service' (such as filing system) ROM's, and more 
       features I could go on listing...! 

      "The BASIC was later upgraded to version 4 (Master) and versions 
       5 and 6 (Archimedes - see comp.sys.acorn.* groups for fans of 
       these machines) - version 6 has IEEE floating point support. 

      "The Z88 and the PC, Amiga versions of BBC BASIC seem to be 
       based on version 2, but only have restricted OS command access, 
       and may or may not have assembler access. For emulating 
       purposes, although BBC BASIC(86) tries to support various 
       graphics modes, the BASIC variants cannot do enough to support 
       a 'proper BBC' environment."

    4.6.1 !6502Em [Acorn Archimedes]

        BBC emulator for the Archimedes. Provides 65c02 emulation, odd

        Does not handle 6522 timers. Written by Mike Borcherds 


    4.6.2 !65Host [Acorn Archimedes]

        !65Host is a BBC B emulator for the Archimedes; it was 
        supplied with RISC OS up to version 3.5. It is a reasonably 
        complete emulation and supports all but the most dodgy ways of 
        accessing the hardware. Images of BBC ROMs (for example 
        Wordwise, View etc) can be loaded and used. Later versions 
        support sound emulation (no mean feat) and allow around 70-80% 
        of BBC games to be played. 

        This emulator was developed and distributed by Acorn as an 
        extension to RiscOS; it may not work with versions 3.5 and 
        3.6, though.

        although an 80486/100 or faster is suggested. 

        You will have to get a copy of the BASIC and OS ROMs to run 
        this emulator. 

        Improvements in version 0.3 include VESA graphics support,

        developed that should work on most other systems. Written by 
        Stephen Quan <>. 

    4.6.7 BBCEm [Acorn Archimedes]

        Runs on an Archimedes. Executes BASIC programs and graphics. 
        There are some buggy opcode implementations in this emulator 
        that occasionally cause it to crash. Written by Nigel 

    4.6.8 BPC [MS-DOS]

        A completely assembly emulator for MS-DOS. This is a work in 
        progress; when complete, it will require an 80486 or higher. 
        The development of this emulator has been set back slightly 
        due to an operating system installation mishap. Under 
        development by Mark Cooke <>. 

    4.6.9 Beeb (1) [Linux]

        BBC emulator for 80x86 machines running Linux. 

    4.6.10 Beeb (2) [Unix]

        C based emulation of the BBC. Currently has reasonable support 
        for the 6502 and 6522. Supports sideways RAM and ROM. Limited 
        graphics support is implemented. Under development by James 
        Bonfield <> and Steve 
        Youell <>. 

    4.6.11 BeebEm [Unix, Windows NT, MS-Windows]

        An emulator for the BBC which runs under Linux, SunOS, and 
        HPUX; it probably will compile for other systems as well -- 
        GCC seems to provide the best results. It has been ported to 
        Windows NT 3.11 and Windows 3.1 with win32s. You need ROM 
        images to run this emulator. Written by David Alan Gilbert 
        <>. Windows port by Nigel Magnay 

        There is also a newer version (0.6) available; it fixes a few 
        bugs, runs faster, and emulates sound. The new version is 
        available for Unix only at the moment. 


        Prerelease v0.6: 

        MS-Windows 3.1 Program: 

    4.6.12 Horizon/MacBeebEm [MacOS]

        Horizon includes instructions on how to make a cable for 
        BBC-to-Mac transfer for about US$4. It was previously titled 

        Note that Horizon cannot run as a BBC Master micro.

        Old version: 


    4.6.13 Owl [NeXTstep]

        BBC B emulator for NeXTstep machines (680x0 and 80x86). Runs 
        about half the speed of a BBC. Implements all non-split 
        graphics modes. It can manipulate a variety of disk images 
        (read only). By Ian Stephenson 


    4.6.14 THE EMULATOR [Amiga]

        This emulator runs software compatible with BBC BASIC 2 and 
        DFS. It runs on its own screen and allows easy transfer to and 
        from workbench programs. It runs BASIC faster than a BBC in 
        all cases, and 6502 assembly slower than a BBC on 68000 
        machines, and faster on '030/'040 machines. It stores files as 
        AmigaDOS files, not disk images. 

        THE EMULATOR supports graphics modes 0 - 7, common VDU 
        drivers, common OS procedures, printing, RS232 I/O, and sound 
        (except the ENVELOPE command). It does not support GCOL modes 
        1 - 3. 

        It will not run poorly behaved programs (ie programs that 
        communicate directly with the hardware.) 

        THE EMULATOR was produced by James Associates in the late 
        '80s/early '90s. It runs as-is on a 68000, and requires a 
        small patch to run on the '020 - '040. It is not known if JA 
        are still in business; their address is/was:

        Alastair Booker <> about the patch: 

        "The best utility I have found for doing this is TUDE 
         (available on Aminet). If you trap the MOVE SR instructions 
         (select PRIVILEGED) and get it to return 1.3-like values on 
         certain OS calls, it works OK." 

        [Reposted with permission] 

        See appendix C for Aminet sites. 

        This emulator was sold as an official Commodore product at 
        some point, but is no longer available commercially. Despite a 
        brief appearance on Aminet, this emulator does not appear to 
        have been released into the public domain. 

    4.6.15 TOL [MS-DOS]

        MS-DOS based BBC emulator, formerly called "My6502." This is a 
        work in progress (ie it does not work yet). Under development 
        by Chris Rae <>. 


    4.6.16 XBeeb [Unix & X]

        XBeeb is a BBC Micro Emulator for UNIX and the X Window 
        system. It is reported to run faster than BeebEm, and can 
        execute many BBC games. The source code (C) is known to 
        compile under Solaris 2.5 and Linux. 

        Features include support for NMOS 6502A and CMOS Rockwell 
        65C02 and 65C12 processors including all undocumented and 
        illegal opcodes, Model A and Model B emulation, almost full 
        support for the 6522 VIAs, mode 7 teletext support, emulation 
        of all bitmapped screen modes (with a few minor bugs), full 
        color support (including flashing colors), preliminary sound 
        support (under Linux/Voxware), FS emulation support (using 
        standard Unix files, not disk images), and sideways RAM and 
        ROM. The author's compatibility testing produced about a 90% 
        success rate. 

        There is a mailing list for XBeeb emulators; to subscribe, 
        send email to <> with a body of 
        "subscribe xbeeb".
