MMN80CPU is a Z80A microprocessor clone, working at 4 MHz. It was produced from 1988 onwards at Microelectronica Bucharest[1] for the Romanian automation industry and 8 bit computers such as HC-91, HC-2000, Tim-S, CoBra, CIP, JET, CUB-Z, aMIC, PRAE and others. It exhibited a unique and unusual behavior: immediately after a reset, it activated the M1 line without using RD or IORQ to reset a PIO controller directly, saving a gate in industrial systems with PIOs.
