      The 816/C version was a multi-user system featuring:\
      \- Dual CPU (8085 + 8088) motherboard\
      \- 384 KB of RAM, expandable to 1 MB\
      \- 2 x 1.2 MB 8" F.D. drives\
      \- 9 serial ports\
      \- 3 to 16 users expansion

      As the magazine 'computer Age' said, this system was almost twice as quick as an IBM-PC.

      We've wired CompuPro savvy into three of the industry most potent new processor chips. 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.

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.
