The dedication of San Francisco-based Systems Concepts Inc to keep alive the old DECsystem-10 and 20 36-bit mainframe architecture with its SC-25 machines has been rewarded with a contract for nine SC-25s over 18 months from CompuServe Inc, which wants them to replace some of its old DECsystem-10s. The SC-25 is a reimplementation of the 32-bit DEC architecture, discontinued by the minimaker in 1983, and can run all the 36-bit operating systems, including TOPS-10, TOPS-20 and Tenex. In case the replacement market for DECsystems proves too small, Systems Concepts is also committed to a version of Unix for the SC-25.
