Ohio Scientific Model 560Z CPU (PDP-8!) - test-drb@ccmp.vtda.org

26 Mar 1999

Back in the old days, somebody or other, I'll look it up later (General
Instruments, I believe), made an LSI which was essentially compatible with
the PDP8-E.  The idea was that it was much less of a maintenance headache to
have the CPU in microelectronic form as opposed to the ssi-msi
implementation commonly seen.

These didn't fare to well on the market because of the rapid evolution of
the commercial microcomputer industry.

...
 I just got another box of OSI marketing lit.
One of the items is a single sheet glossy
with no date, but showing C1s C2s and C3s.
Since there is no mention of anything else,
I assume it's from 1977.  Here's the kicker:
It lists a Model 560Z CPU board with PDP-8
code compatibility!  Has anyone on the list
ever seen or heard of one of these?

Thanks,
