Hi,
I finally brought home the Compupro CPU box. I'm surprised how clean it
is. It looks like new. The only thing I found wrong so far is one wire
broken off of the backup battery holder. Here's what's in it:
21 slot backplane, #194 Disk 3 card (hard drive controller), Disk 1A card
(5 1/4 and 8" floppy drive controller), #187 Interfacer 4 card (parallel
and triple serial ports), #162 System Support 1 card (serial port to
terminal, interupt controller, RTC, Math Co, 4K SRAM, etc), CPU 8085/88
card (both 8088 and 8085 CPUs), #816 RAM 22 card (with 256K SRAM), two RAM
23 cards with 128K SRAM each.
I dug through my manuals and found manuals for the Interfacer 4, RAM 23,
CPU 8085/88 and System Support 1 cards. I still need manuals for the
chassis, RAM 22 and both disk controller cards. BTW I have extra copies of
the above 4 manuals. I'll trade them for the manuals I need.
At 12:36 PM 5/8/99 -0400, you wrote:
There's no red switch or anything marked "speed" on this card. FWIW the
CPUs are 8088-1 and D8085AH-1.
OK It's listed above. Thanks.

I picked up a
Compupro 816 computer yesterday and an external drive unit
with a hard drive and an 8" floppy drive. I haven't brought it home yet so
I haven't taken more than a quick look at it. Can anyone tell be about the
computer and drive? What CPU, speed, etc. What kind of operating system it
uses, etc.
If it's using the same CPU's it shipped with, it has a 8085A and a
8088A on a 85/88 CPU board. Speed is 2 or 5 MHz, depending on what
the big red switch labeled "SPEED" on the CPU board is set at.
Of course, it's a S-100 box, so just about anything could have been
dropped in at either the factory (special-order), the Compupro dealer,
or by the end user.
Typically the system either ran CP/M-80, CP/M-86, or a special
Compupro version that was basically CP/M-86 but would also run 8-bit
executables on the 8085.
There were many aftermarket CPU's available, some with 80286's on them
and 8 MHz Z-80's, that were commonly dropped into Compupro chassis.
I haven't brought home the drive box so I don't know what's in it yet.
I don't see a keyboard or video connectors so
I assume it needs
a terminal to talk to it.
Very likely, yes. Most likely, it has a System Support 1 board
with console serial port, clock, and interrupt controllers. But there
are lots of other ways to set up a S-100 system.
Does any have a pinout of the serial port so I
can make a terminal cable.
Look for a 25-pin cable from the System Support 1. It's plain old
RS-232. Depending on which OS and version you run, and how it was
generated, you might need to assert DTR.
What size is the hard and floppy drives
You tell us :-). A Compupro 816 most likely shipped with a Qume
Datatrack DSDD 8" floppy drive, a bit over a Megabyte, most likely
hooked to a Disk 1 (or 1A or 1B or 1C) controller in the S-100 chassis.
The hard drive is likely a MFM drive, anywhere between 5 and 30 Megabytes,
hooked to a Disk 3. Again, just about anything was orderable/configurable. does
the floppy drive use hard sectored disks, etc etc, etc.
Almost certainly soft-sectored disks.
I noticed that
there are connectors for both a 5.25" and an 8" floppy drives and another
for a hard drive on the back of the CPU box. Does anyone have a manual or
the OS software for one of these?
Sure. I bought out the last Canadian Compupro dealer while I was in
Vancouver and have manuals, configuration software, etc. Let us know
what's *in* your box and you'll get more details.
