Utilising the powerful 4MHz Z80A Microprocessor the GM811 CPU card can be used as elthera stand alone controller or as the heart of a compiex microcomputer system. Four ‘Bytewide’ sockets allow great flexibility in the type and size of memory devices chosen. input and output facilities include both programmable serial and parallel interfaces – RS232, 1200 boud CUTS cassette interlace, Z80A PIO, and an eight bit input port. inan expanded system the unique on-board RP/M monitor allows the creation of cassette or Eprom based programs or files which ore upwards compatible witha disk based CPIM system.
