1.0 What the group is about

1.1 What the group is about

This group was formed for the discussion of homebuilt computer hardware, as
the name implies. The term "homebuilt" or alternately, "homebrew", refers
to the hobby of building electronics at home, generally with a soldering
iron or wire wrap. No knowledge or experience is required for posting to
this group. Postings may deal with real hardware, or absract concepts, and
are not restricted to any specific cpu or architecture. Topics may also
include homebuilt peripherals added to existing off the shelf systems, or
hardware hacks to existing systems/accessories.

Please note: Unfortunately, the term "homebuilt" causes a great deal of
confusion amongst IBM clone builders, which leads to a large number of
inappropriate posts on this newsgroup. This group, as a general rule, is
not for discussion of IBM related hardware, unless there is some aspect of
home built electronics involved, such as connecting your own device to an
IBM serial/parallel/game port, etc. or using IBM clone hardware as part of
a homebuilt design (non-IBM design). Common IBM clone hardware hacks, such
as overclocking and changing the UART chip, are best discussed in one of
the IBM related newsgroups. An IBM clone hardware questions pointer is
posted frequently on news.answers, and due to its length the information
within it will not be repeated here.

Warning: Any post that may be considered an "" post is likely
to draw flames or intentionally misleading advice from the regulars at
a.c.h.h. Following such advice for a "fix my PC" type post may be damaging
to your computer. You have been warned.

1.2 How to Deal With the Cancelbot

Because of excessive noise (mostly involving off topic "fix my PC" type
questions) a cancelbot has been set up on this newsgroup. Failing to inform
the cancelbot that you have read the posting rules may result in your post
being automatically cancelled. To let the cancelbot know that you are aware
of the posting rules, you must add the letters "PRR" (without the quotes)
somewhere in your first post. PRR stands for "Posting Rules Read". These
letters do not need to be included on subsequent posts.

Questions or comments about the cancelbot should be directed to

1.3 Who is "PRR"?

See the previous section. Some people mistakenly add PRR to every post
(only your first new thread needs these letters). Some people have mistaken
it for a signature. Because the letters may be included anywhere in the
post, some people have taken to creative uses of the letters, which include
the fabrication of information about a mythical person with the initials
PRR. At the time of this writing, PRR has been in the hospital, and is
known to have an affection for Milk Duds. New readers are free to
contribute to this on-going "story".

2.0 Questions

Answers to specific questions are included in this section. Many of the
answers are only pointers to more information, so that large volumes of
information are not duplicated unnecessarily.

2.1 Can I post ads on the newsgroup?

As a general rule, alt.comp.hardware.homebuilt is not a forsale group and
thus does not allow advertising. An exception is made for advertising that
is directed specifically for electronics homebuilders, and is not otherwise
available on the net in general. Examples of this are device programmers
and electronics parts. Trading between homebuilders is encouraged.
Items that fit well into other existing forsale newsgroups should not be
advertised here. PC related advertising, such as hard drives, motherboards,
and other standard PC clone parts, is not permitted. While CPU
advertisements in general are permitted, CPU advertisements for the common
PC clone CPU's (such as 486 and Pentium chips) are not permitted because of
the existing PC clone forsale groups that already provide plenty of
coverage for these parts.

2.2 Can I post questions involving hardware problems?

This question was asked to the group in general, and the overwhelming
response was NO! The only exception would be if you are having a hardware
problem with your homebuilt hardware, not pre-fab hardware. As Andrew noted
in an early version of the FAQ:

"Since EVERY SINGLE ONE of the replies I got re: the FAQ said "no, this is
not the appropriate place for questiongs about PC building and pre-made
parts and compatibility between them, the answer obviously is a very strong
NO. This is not to say that you should not post questions, but only post
questions about homebuilt computers, not computers built from pre-made
parts. The difference should be very clear. If you post here about your
hard drive that you want to slave, i doubt if people will have much mercy.
It is getting on peoples nerves."

Replies to PC hardware problems are also strongly discouraged. Such replies
should either be posted on the appropriate groups or should be done via
private e-mail.

2.3 What's this about a new homebuilt newsgroup?

It has been suggested at times (often sarcastically) that a new newsgroup
should be made up with some name other than alt.comp.hardware.homebuilt, so
that the group would not be plagued with off topic pc-clone related posts.

A newsgroup specifically for "homebuilding" in the PC clone sense of the
word (alt.comp.hardware.pc-homebuilt) has been created. All PC questions
should go to that newsgroup.

alt.comp.hardware.homedesigned was created in an attempt to provide a low
noise alternative to this group. It has since been abandoned.

2.12 How do I make my own circuit boards?

There are several methods available. Most involve etching, where a mask is
drawn or transferred onto copper clad board, and the board is immersed or
sprayed by an etching solution. Boards and etchant can be purchased at most
electronics hobby stores, and various manufacturers products are available
via mail order. Some methods use iron-on transfers, and others use a
photo-etching process. There is even a method using conductive ink and
laser printers. Some people have reported good results using Vector wire
and Verowire (UK). These methods are more similar to wire wrapping than PCB

the software packages are designed to allow the user to enter a schematic,
test the circuit, and provide an output that can then be used to directly
fabricate the PCB (either an electronic format or an actual printout that
can be used for etching).

2.13 What is the Net Station?

The Net Station was a project whose goal was to create a computer
architecture and operating system that would be freely distributed on the
net. An agreement on the architecture, etc. was never reached, and the
project seems to have been abandoned. The thread does see occasional
revival, but little practical progress has been reported lately (to the
group, at least). There are unconfirmed reports that the project is still
being worked on, but details are presently unavailable.

2.20 How can I make a mouse serial/ps2 or ps2/serial adapter?

Serial mice and ps2 mice do not use the same type of communication. Some
mice can detect which type of port they are connected to, and adapters for
these are not standard. Consult your specific mouse manufacturer to find
out if an adapter is possible, and the necessary pinouts.

Microsoft and Logitech have produced mice useable in serial and PS2 ports.
