** Two of
the S-100 homebuilts are actually complete TRS-80's
implemented on S-100 cards - they run the TRS-80 ROMs unmodified
(with disk system) and load/run TRS-80 software!
Holy crap II! That is fucking cool! Pictures!!!
I thought so too - Very unique S-100 systems - I will be getting them
up and running, and will let you know how they work out. They
are mostly
homebuilt cards (except for memory).
I want pictures of those homebrew TRS-80 S-100
systems.
That has to be
the coolest S-100 system ever (next to the Atari
S-100 stuff
I've got ;)
Are these Z80 TRS-80 systems, or the 68000 systems? There actually were some
S-100 like systems (same connector, different board form factor) of the
model 16/6000 series. They were used in large (for the time) dialup systems.
I think they had 2+meg of ram and 2 or 3 four port serial cards. I have
never seen these, only heard about them.
I think I may have one of these. Years ago I picked up a large metal
chassis that I was told was a TRS-6000 and IIRC it did have TRS cards in it
but it was NOT in the usual plastic chassis (I have one of them too). I
pulled it apart and looked at it and as best I can remember it has 3 Mb of
RAM, a 68000 CPU and a Z-80 CPU and a LOT of serial ports. I also got a
huge stack of TRS-6000 disks and docs with it. I thought perhaps it was a
TRS-6000 that someone had taken apart and mounted in a metal chassis but
your message makes me wonder. It's been years since I looked at the thing
and I don't remember what form-factor cards are in it.

Some were even modified to run
68010 CPUs. There are instructions out there somewhere
for this mod, but
no-one seems to have them readily available. They "lore" is that these
instructions were saved in the swap area of one of the install boot
diskettes. I was able to find and extract the games that were hidden there,
but never these instructions.
