Digital Systems
Digital Systems Inc., was an American accounting service and technology development company active between 1966[1] and 1979.[1] It was founded by John Q. Torode in Seattle, Washington.[2] [3] [1] [4] [5] The company was reorganized into the microcomputer design and development company Digital Microsystems, Inc. (DMS),[5] Oakland, USA, founded in 1979.[6] In 1984, it was sold to the new UK operation Digital Microsystems Ltd. (DML) (owned by Extel Group Plc)[7] and finally ended its US operations in 1986.[1] [5] Without Torode, Digital Microsystems Ltd.'s product HiNet (Hierarchical Integration Network) was sold to Apricot Computers Plc in 1987.[8] In 1986, Torode founded a new company, IC Designs, Inc., based partly on Theodore "Ted" H. Kehl's VLSI technology at the University of Washington (UW),[1] [9] which was bought by Cypress Semiconductor Corp. in 1993.[9]

[...] The first commercial licensing of CP/M took place in 1975 with contracts between Digital Systems and Omron of America for use in their intelligent terminal, and with Lawrence Livermore Laboratories where CP/M was used to monitor programs in the Octopus network. Little attention was paid to CP/M for about a year. In my spare time, I worked to improve overall facilities [...] By this time, CP/M had been adapted for four different controllers. [...]
