From the project
Neudesign des Mikrocomputers M.Kramer
Bisher sind folgende Baugruppen realisiert: - CPU mit RAM und EPROM - BWS mit 2K Zeichengenerator - Floppycontroller mit u8272 (nach FA 07/1990) - Grafikdisplaycontroller mit U82720 (nach FA 07/1990) - 2PIO - SIO mit U856, U857 und 8251 - Backplane mit 8 Steckplätzen
Alle Baugruppen können mit EFS 29 (A-B oder A-C) Steckverbindern oder alternativ mit DIN 41612 C 2*32 bestückt werden.
