[3] An optional correlation and filtering unit (CFE) can be added, which is capable of very fast floating-point multiply-add operations (primarily intended for digital signal processing applications).
A free-standing console is also provided, which includes binary displays of the machine's registers and switches to boot and debug programs.
The normal variety of peripherals is also available, including magnetic-drum units, card readers and punches, and an extensive set of analog-digital/digital-analog conversion devices.
Speed is good for its cost, but with an integer add time of 3.5 microseconds, it is not in the same league as the scientific workhorses of the day (the CDC 6600, for example).
[4][5] Towards the end of the SDS 930's market lifetime a real-time monitor system was introduced, which included a FORTRAN IV compiler.
Early flight simulators used the SDS 930, because of its hardware integer multiply and divide capability and its real-time data acquisition and control peripheral modules.
