If you are interested in getting rid of your Compupro Components, I would be interested in having them.

I don''t know if this is allowed on this Forum, but I''ll post my email address for you to contact me.

The 8085/8088 Dual Processor Board was also available in a 6Mhz/10Mhz Version, which is many times slower/slower in throughput than the 6Mhz 80286 3-cycle Processor Board that Compupro produced. The fastest 16-bit processor offered by Compupro was the 2-cycle 12Mhz 80286. Compupro went as far as putting the 80386 Processor onto the S-100 bus before the Company folded. The most advanced Operating System offered by Compupro was Digital Research''s Concurrent DOS, which could be configured for multi-processor, multitasking, multiuser operation with MSDOS compatibility.

Minor correction. The dual processor card, "CompuPro 816", was a 6 Mhz 8085, 8 Mhz 8088 pair (only one processor active at a time).

Typically used with either CP/M-86 (16 -bit CP/M, 8085 not used) or CompuPro''s "CP/M 8/16", a modified version of CP/M-86 that would automatically create an 8 bit CP/M instance and transfer control to the 8085 whenever the user launched an 8 bit program, and return control to the 8088 when the program ended.

I have a CompuPro 8/16 used in the Digital Research Dallas sales office for about two years before being put in storage (in the mid 80''s). Is there interest in this system? It seems complete (with documentation). It includes a S100 card cage module (with power supply) and a dual-drive 8" floppy drive module. I also have unpacked about 500 lbs of documentation, manuals and CP/M boxed (and loose) software.
