Description
Introduced in March of 1983, the CompuPro S-100 system was one of the last and most expensive CP/M systems that appeared at the end of the S-100 bus and 8 bit professional era. It was a very flexible system that could accommodate a wide range of S-100 bus cards built by a wide range of manufacturers.
Compupro itself manufactured a large number of S-100 cards. Its S-100 system could be fitted with either 8-bit and/or 16-bit processor cards. One of the best-selling cards was a dual processor 8808 + 8085. This allowed running both 8 bit CP/M and 16 bit MP/M software at a speed of 2 or 5 MHz in a multitasking environment.
The CompuPro S-100 included several cards from 8088/8085 to Z80 to 80286 at a speed of 4 MHz and up. There are 2 8"floppy disk drives. The three major options for operating systems were CP/M, CP/M-86, MP/M and others. It has 16KB of RAM which could be expanded to 1MB. Depending on how the computer was configured, its price ranged from around $5,500 up to almost $20,000.
