Interface M/P

A parallel interface from 1990 produced by Didaktik Skalica for the Didaktik M computer for connecting peripherals. It contains its own EPROM memory with a capacity of 16KB and a parallel input-output circuit 8255. The software stored in the EPROM memory enables communication with peripherals with a Centronics interface and BT 100 or Gamacentrum 01 printers. When working with a computer in the BASIC language, there is no need to record to operate the device utility program from a tape cassette. This interface can be used with its own program support to communicate with any device and is a useful addition to the Didaktik M computer, expanding its useful features
