This info was obtained second hand from a guy I bought a bunch of
SCP stuff from. Apparently a one-time friend of his work for them.
Thus - this could be wrong. SCP made at least six models of computer
the first being Z80 machines which ran CP/M, the next few being 8086
based which ran CPM-86 or SCP-DOS (which I'm pretty sure is MS-DOS
1.0 or the immediate prdecessor purchased by MS). The last were 8088
PC-clone type machines. We're concerned with the 8086 machines which
apparently were equipped to take a coprocessor so as to run both
CP/M-86 and SCP-DOS/MS-DOS simultaneously. I missed buying such a
machine by 15 minutes :(. At any rate - I'm guessing you have a
bunch of 8088 co-processors for these machines. The one I missed
was called a Gazelle-I so they might be for that machine.
Too bad I missed the machine - but I did pick up everything else the
guy had. Came down to a stack of Shugart 8" drives, some CompuPro
S-100 boards and a whole bunch of SCP disks. Now that I've brought
it up - SCP-DOS 1.0 = MS-DOS 1.0? I'm pretty sure it is because
another disk I've got is labelled the same but says SCP/MS-DOS v1.25.
