Systems Concepts

Systems Concepts was a company (originally located in San Francisco) which built custom hardware, initially for KA10 PDP-10s. It was founded by Stewart Nelson and Mike Levitt; in 1970, Peter Samson joined them as Director of Marketing.

Among their early products were the DK-10 asynchronous serial line interface, the DC-10 and SA-10 disk controllers, and the DM-10 paging box for MIT's KA10 ITS machines.

Later on, they designed the SC-40, a high-performance PDP-10 compatible machine, after DEC cancelled further PDP-10 replacements.
