Is the Interface OK?
T Suresh · IETE Journal of Education · 1990
When a peripheral device fails, software methods can be initially resorted to before the usual hardware test procedures are used. A test program is presented here that allows various peripherals, inter-faced to a Norsk Data computer, to be tested. The program illustrates the use of some essential monitor call routines, and can be used to develop driver routines for Norsk Data peripherals.
