The SC-40 was a PDP-10 clone from Systems Concepts; their last PDP-10 product. A single processor SC-40 ran at up to eight times the speed of a single processor KL10.
Its CPU was microcoded, with 32K 80-bit words of read/write microcode RAM; it had a 32K-word write-through cache. Main memory (semiconductor ICs) was protected with ECC, to allow single-bit error correction and double-bit error detection.
Numerous I/O peripherals were available:
- an IBM-compatible channel interface;
- a dual-ported SCSI interface;
- a Computer Interconnect interface;
- an FDDI interface;
- an Ethernet interface;
Each SC-40 included a SPARC microprocessor front end, which performed console functions such as loading the microcode, and diagnostics on the entire system.
