The S/23 I displayed at VCF 5 (2 drives, 96K RAM) can be seen in the following
photo from the show, partially obscured, on the right.

Chris,
are you talking about the sys/32?
If it can sit on a desk top and has a keyboard and green display then
it's a system/23 (also known as DataMaster). It used an 8085 processor,
had 128K of ROM and upto 128K of RAM. It used bank switching to be able
to access that much ROM and RAM.
It has a base of 32K RAM and one 8" floppy drive. The case could hold a
second (both drives were vertical). The case design was similar to the
5120. Even though it used an 8085 all of the character coding was in
EBCDIC.
It ran a BASIC interpreter that was compatible with the basic on
system/34.
It was developed by IBM between 1979-1980 and was a milestone for IBM
because it used a non-IBM processor. It paved the way for the IBM PC
(many of the team that worked on system/23 went on to design and develop
the PC).
i have never heard of the sys/23.
i do have some sys/32 disks - not the ones you
mentioned, though.
i still have the manuals (tech binders) with the
schematics and trouble shooting stuff and i may have
the sys/32 ssp and a few other disks around here
somewhere.
i still have two sys 34's and one sys/36 in my
collection - one of the 34's and the 36 are rare
config's - they both have extended chassi's and extra
hard (disk) drives in them.
the 34 has 2 hd's and the 36 has three hd's.
it's really interesting that the 34 has 8 inches of
chassi added to it and the 36 has three feet of chassi
added to it.
i do have alot of sys/36 software and some sys/34
software.
if you do have a sys/32 - you can have the manuals and
software - just arrange shipping.
i no longer have a sys/32 and no longer need the
stuff.
