The result: more performance, more quality, more reliability, and higher speed for greater throughput than ever before.\ CPU 286 and CPU 16032 can upgrade present systems to state-of-the-art operation, or serve as powerful fundations for new systems. CPU 68K, aside from being a superd CPU board, is also the core of our system 816/68K.\ As always, CompuPro kept an eye on the future in designing these CPUs. With a CompuPro, you don't shudder a fast-changing technology, you welcome it. We give you brains and brawn in one box, and that's beautiful. image: null hardware: - title: Z80 CPU CARD subtitle: '' text: This card could be used alone or as a slave card to run 8-bit tasks in a 16-bit system. image: null - title: INTEL 80186 CPU CARD subtitle: '' text: |- With this board one could have 2 seperate 16-bit CP/M sessions running, each with their own 64K or 256K of RAM.\ This card is fitted with 512 KB of RAM image: null - title: INTEL 80286 CPU CARD subtitle: '' text: '' image: null - title: 16032 CPU CARD subtitle: '' text: 16-bit National Semiconductor's 16032 processor board.

I do not know if this is the proper forum for this. This belonged to my father and I am in the process of settling his estate. I have posted pictures of the system components. If anyone has any interest or advice on how to proceed, please feel free to contact me. - author: Taraku (USA) date: Sunday 24th April 2022 text: I''m soon going to be working on the system, and will be doing upgrades to it as well. If everything goes well, I hope to start making videos online. I want to see if i can make a old computer do new tricks. as well as teach people 74 series logic. I hope to reach out to someone that may be willing to donate parts for this. I want to make a all original and one that is fully upgraded. I want to start with this system first because, not many people know what this pc is. - author: Michael Louie (United States) date: Sunday 3rd September 2017 text: |- William (Bill) Vaughn (Redmond, WA USA) If you are interested in getting rid of your Compupro Components, I would be interested in having them.

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. - author: C H Jervey (South Carolina, USA) date: Wednesday 30th August 2017 text: |- 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. - author: William (Bill) Vaughn (Redmond, WA USA) date: Sunday 17th August 2014 text: 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. oc_id: 651 source: url: https://web.archive.org/web/20230603023358/http://www.old-computers.com/museum/computer.asp?c=651 date: '2023-06-03' --- The Compupro 8/16 system was one of the last, big, expensive CP/M system that appeared at the end of the S-100 Bus and 8-bit professional systems era. It was actually a typical S-100 box where the user could insert almost any S-100 card build by the manufacturer or anybody else. As Compupro manufactured a large range of S-100 card, the system could be fitted with either 8-bit and/or 16-bit processor cards. One of the best-selling card was a dual processor 8088 + 8085 that allowed running both 8 bit CP/M and 16 bit MP/M software, at a speed of 2 or 5 Mhz, in a multi-user, multi-tasking environment. Several advanced CPU cards were available later: Z80 at 8 Mhz, Intel 80286 and National Semiconductor 16032. Due to the large range of available CPU cards, practically all operating systems and programming languages of the time could be used. It appears that Compupro still exists and offers a limited support, spare parts and manual hard copies.
