Heck with everything all on one mother board your lucky if you can
change the video card.
%$!@ old PC , $#!@ new games that want the latest video.
I remember checking into the homebuild newsgroup,
thinking maybe they
were wirewrapping TTL together or something cool.
My ISP does not seem to suport news groups any more, so I can't say
what is being built.
How about changing the name to alt.I've.added.lights2my.case. I notice
here in Canada
Radio shack has got away from selling almost any kind of real
electronic componemts but
it shure has a lot of small light bulbs and big heavy switches.

So were you planning to build a computer?
If so what kind?

Well, I'm the kind of nerd who considers it a challange to identify a
74xx TTL chip that I haven't seen before, but I'm getting very mired in
all sorts of projects now. I'm looking at various micro-based designs
now. One that I've actually wired up that is 8088-based, but I haven't
plugged any code into the EPROM socket of it yet. The one that people
here would find more interesting is a IM6100 based system. I acquired a
number of tubes of the Harris-clone of the 6100 processor awhile back,
and want to cobble up a single board design. Theres' already the
far-superior 6120-based design that runs the actual full-blown PDP-8
software like the operating systems and FOCAL and what-not. My 6100
design would be for running hand-assembled machine code, and 4K only
(the 6100's 12 bit address bus and all that)
I don't think I posess any 74181 ALUs anymore to 'really' roll my own
system. Lots of 4/8-bit latches and coder/decoders on hand, though.
Who would want to be without some of that stuff for general purpose
projects?
Right now the path to the bench with the soldering iron on it is
obstructed by a huge pile of misc. gear that NEEDS to be dealt with, and
soon.
