Args OS 3 CRC32: 0x5B1EADF3
- Mostly a copy of the REV 2 XL rom, but boasts a ROM disk driver by Ralf
David that activates by holding Select while resetting. How this works, I have
no clue. ARGS stands for Atari Regional Gruppe Stuttgart. Need extra info on
this one.

Bibomon V2.1 (c) 1084/85 E. Reuss CRC32: 0x41B80C28
- Option + Reset enters a built in machine language monitor. Also some colors
have changed. Looks like Basic is disabled by default, and no way to enable
it.

Highchip (c) Irata GmbH 1985 V.1.9 CRC32: 0x41BB4047
- Mostly a copy of REV 2 XL rom, but includes Happy Warp Speed boot and
changed colors. Special options menu can be initialised by pressing Option +
Select + Reset. Pressing Select + Start while booting, boots from casette.
Booting while holding Start tries to initialise Warp speed before booting.

Oldruner CRC32: 0x10ABFD80
- A copy of the OS-B for the 800, but tweaked to function with the XL/XE line
of computers. Makes the XL/XE line able to run 400/800 software.

Omnimon 87 CRC32: 0x9B4F8FAD
- Byte Eaters OMNIMON V_r 1987: Added monitor, through Select+Reset, which
replaced the self test, as was pretty much the standard at the time.
Compatible with most 800 software. Classified as translator rom.

Omnimon XL CRC32: 0xBFA09B66
- David Young OMNIMONXL (C)1984: Added monitor, through Select+Reset, which
replaced the self test, as was pretty much the standard at the time.
Compatible with most 800 software. Classified as translator rom.

Omnimon XE CRC32: 0x64B77137
- David Young OMNIMONXL (C)1984: Added monitor, through Select+Reset, which
replaced the self test, as was pretty much the standard at the time.
Compatible with most 800 software. Classified as translator rom.

Omniview 5 CRC32: 0x5987F5D8
- (c) 1985 David Young. Based on rev B 800 rom. The extra 6kB holds the main
feature: A 80 column E: handler that can be invoked from most programs
including basic. This mode uses a Graphics 8 screen, with a 4-bit wide font.
Not the best readability. Manual includes patches for (at the time) well known
word processor software: Speedscript 3.0.

Omniview 6 256K CRC32: 0xEB0C62EB
- Only difference with Omniview 5 is a change of tagline. David Young tagline
is replaced by the message "    OS-80+ ext.256K rev.(C)1986". There is no
extra support for additional ram. I suspect it's a rip-off.

Omniview XE CRC32: 0xE4BF5B98
- (c) 1985 David Young. Very alike Omniview 5. Same base, same feature, but
with a reworked character set, which is a slight bit easier on the eyes. Minor
changes in the code.

Pud CRC32: 0x95EC9329
- Proof of concept rom for a Power-Up display, made by Aegaeis Softscape.
There might be many versions of this now, because it was advertised to sell,
tailored to suit anyone with a name to stick in. Has no SelfTest, since that
area is replaced with custom graphics/routines for the power-up display. Based
on XE rom. Fully compatible. 
- If booted with Select, the startup screen will be skipped. If left by it's
own devices, the startup screen will show for about 2.5 seconds. If  Select is
pressed in that time short time, it'll continue to show until Select is
released again.

Q-Meg V2 CRC32: 0x51939D37
- Q-Meg OS versions incorporate a Machine language monitor, support for
ramdisks, including BOOTING from them, without the need for a separate ramdisk
driver. HIO (high speed SIO for Speedy extended drives) is built in aswell.
- Compatible with the XL/XE roms for normal use. Not recommended for emulators
for all versions.
- Lower versions can adress drive 1-4 and 8, later ones can adress drive 1-8.
Configurable ramdisks with 256kB of memory can be either 2 single density
drives, 1 enhanced drive + one small x-drive, or one double density drive.
- Ramdisks may be filled from disk directly from the menu, aswell as written
to disk, including formatting. They can also be protected from being
overwritten by other software. Also Basic can be turned on/off.

Q-Meg V2.3 CRC32: 0xA1FB9BFA
Q-Meg V3.0 CRC32: 0xBE14E47E
Q-Meg V3.2 CRC32: 0x8CD48719
Q-Meg V3.8 CRC32: 0x78F2C102
Q-Meg V4.2 CRC32: 0x64CCFC53
Q-Meg V4.3 CRC32: 0xBE2442DA
Q-Meg V4.4 CRC32: 0x0547F499

Speedos CRC32: 0xA991769B
- I totally have no clue what this does, it just makes my computer crash like
there's no tomorrow. I get the feeling this has Happy extensions that my
drives just don't like, or something like that...

Supermon '85 CRC32: 0xBBD8A8BD
- All Supermon versions are based on the 800 rom, as far as I've noticed so
far.
- Machine language monitor through Select+Reset.

Supermon 2.0 CRC32: 0xFFDC4372
- This one is probably a rip off of the '86 version, as only the monitor
tagline differs.

Supermon '86 (BRD) CRC32: 0x28DD9BE4
- Same as Supermon 2.0, just gives a german header when invoking the monitor.

Supermon HTT CRC32: 0x1101FF93
- Same as Supermon '85, with different colors and charset. Modified build for
the High-Tech Team, a demo/developer group from the Netherlands.

Warpcopy CRC32: 0x21A89311
- Warp speed Happy extension included. Need extra info on this one.

Xos CRC32: 0x196C9B00
- Never found out how to get into special functions on this one yet. Need
extra info on this one.
