Computer report VI: Minicomputer interfaces: Know more save more: When a standard interface won´t do the job, you can pay for a custom design ¿ or do if yourself

Discusses custom design of the peripherals required to complete a useful system: input/output devices, mass storage units, etc. Interfaces contain address decoding logic since many interfaces may attach to the same I/O bus. Since processors usually run at speeds much greater than peripherals, the interface is required to act as a synchronizing unit during data transfer. Level conversion, command decoding, multiplexing, and data request logic are all interface functions.
