I have a 5870-121 that I snarked recently, with 4 megs of RAM and a
120M ESDI drive. I'm wondering what I want to put on it as OS. I have
plenty of Linux/NetBSD critters. I was thinking OS/2, but I threw v3.0
Warp on Saturday night, but it's slow as dirt with 4 megs. Oh, yeah. It
had the original reference disk in the floppy drive. I think that's
really why I bought it.
I also have a Model 25 386dx/16 which is one of my favorites. It had
a token-ring ISA adapter, as well as an 8-bit ethernet adapter I can't
ID, no hard-drive, and was set up to netboot. I finally found the J-leg
387 for it, stuck in a 500m drive with EZ-drive, and run PC-DOS &
Lemmings, mostly. >>
The 8570 you have is not bad, but way too small and not really easy as far as
drive expansion goes. put the max amount of 16meg memory in it and os2 will
thank you. mod80 is much better for expansion. that 386 8525 is neat, but not
really rare. I wouldnt consider any PS/2 rare except for maybe the PS/2 E
which I would just call uncommon.
Happy Festivus!

Story of my mom's life -- she was a master of the soldering iron, and
top-of-the-line at Convair (wiring electrical harnesses in aircraft) and
Swan (assembling transceivers). She had to work quickly, there was no
margin for error, and she never made diddly, money-wise.
I'm really grateful that she taught me how to solder at an early age,
though ;>)

All of the above, though I believe the predominence of ASCII for IO
had a big impact and even IBM coding {EBDIC???} wanted around
8 bits.

ISZ was expendable though very useful. The PDP-8 style of IO however
was where a lot of the power in that machine was hidden. You could
seriously extend the machine there.

Bent in that you might want a load to always be some opcode and
a logic change down stream makes it something different do to gating.
A PLA or Prom to translate opcodes from a irregular pattern
of hardware convenience to something regular is handy.
Besides with 48 bits of ucode the address of the next instruction is
in the ucode and the logic is a really wide prom with a really wide
latch and a really simple next address select logic (some LS257s).
No counters or incrementors, The translated opcode from the prom
was the source of the high order ucode address after a "next
instuction fetch". Made the ucode very simple though not very
efficient in terms of bits. Eproms though slow made it cheap with
bipolar proms as follow up for speed.

I kinda figured that. Just like I prefer Z80 opcodes to 8080 as they
are more regular in format.

Polled loop has speed requirements and the problem of what to do
if the FDC never sees dat and has to error out.

The last design I did that way save for ram was cheap by then so
I did a full track buffer.
