Title: V20-MBC: a V20HL (8088 + 8080) or 80C88 CPU SBC running CP/M-86 and CP/M-80 Post by: Just4Fun on June 23, 2020, 11:30:06 11:30 The V20-MBC is an easy to build V20HL (full static CMOS version) or 80C88 CPU SBC (Single Board Computer).
It has an optional on board 16x GPIO expander, and uses common cheap add-on modules for the SD and the RTC options. It has an "Arduino heart" using an Atmega32A as EEPROM and "universal" I/O emulator (so a "legacy" EPROM programmer is not needed) programmed with Arduino IDE. (https://i.postimg.cc/Px3NNL8K/V20-MBC.jpg) It is compatible with the uTerm (https://hackaday.io/project/165325) and uCom (https://hackaday.io/project/165709) boards.
