1.0             General Information

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

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 "alt.fix.my.pc" 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 achhbot@morra.et.tudfelt.nl.

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
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 

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.

For a complete treatment of IDE interfacing to 8-bit
CPUs (particularly the Z80 family), check out issues 56, 63, 64,
and 66 of  The Computer Journal.

There is a simple IDE interface for the Z80 called GIDE (Generic IDE).  
It should be possible to adapt it to other 8-bit processors.  There is an 
article about it on the TCJ Web Page, http://www2.psyber.com/~tcj/.

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 fabrication.

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
