Three chips: a 68008, an SRAM and a PIC. That is the whole computer in the Lite version of the 68k-MBC, and it runs CP/M-68K.
Builder Just4Fun’s trick is the PIC18F47Q10, which does two jobs. It holds the boot ROM and it emulates the I/O the 68008 needs, which also spares you an EPROM programmer. The Lite build takes up to 512 KB of RAM, one serial port and I2C, with an optional SD card and real-time clock. A parallel printer adapter is available. It is an all through-hole design, so a soldering iron is all you need.
Not new, but newly entered
The project page dates from March 2021 and is marked complete, with hardware files, software and documentation. The news is that Hackaday featured it on 2 October as an entry in its 2026 Retrocomputing Challenge, which accepts entries until 27 October. The project describes 128 KB, 512 KB and 1,024 KB configurations across its builds; 512 KB is the ceiling for the three-chip one.
Is a computer whose PIC supplies the ROM and the I/O still a 68008 machine, or a PIC with a 68008 attached?
