2026 Retrocomputing Challenge: A Homebrew Computer In Only Three ICs

A homebrew single-board computer called the 68k-MBC, built by hobbyist [Just4Fun], uses a Motorola 68008 CPU and runs CP/M68K or standalone executables. Its "lite" configuration needs only three ICs: the 68008, an SRAM chip, and a PIC microcontroller that doubles as ROM, limited to 512 KB RAM and one serial port. The "full" version adds a second serial port and supports SD-based storage, RTC, and parallel printer adapters. The project is an entry in an ongoing retrocomputing contest with entries closing October 27th.
