Just-for-Fun Fabio Defabis MBCs: Z80-MBC2, V20-MBC, 68K-MBC
All well described on hackaday:
I bought these assembled from Giovanni Pirozzi. Excellent products and service!
Just-for-Fun has published designs for small MBCs, I ahev three of them: Z80-MBC2, V20-MBC and 68K-MBC.
All with a modern controller for startup and ROM and I/O and SRAM and a real CPU: Z80, V20 and 68008.
All with a SD card and a RTC, all running a variety of Oprarting systems, like CP/M, CP/M-86, CP/M-68K or UCSD PaScal and Basic. All can be programmed with e,g either Turbo Pascal (Z80, V20) or Pascal-MT+ (Z80, V20, 68K).
The user interface is via a serial interface, like USB serial to a PC emulator (Teraterm, Putty, Minicom) or standalone with the Ascii Video Terminal or the FABgl teminal solutions.
