2026 Retrocomputing Challenge: A Homebrew Computer In Only Three ICs

Homebrew computers don’t have to be retrocomputers, but [Just4Fun]’s all-through-hole, 68008-based “68k-MBC” certainly qualifies, so it is a worthy entry in our ongoing contest. While there are both “full” and “lite” hardware configurations, the three-IC “lite” configuration is what first caught our eye. Yes, three: the 68008, an SRAM chip, and a PIC microcontroller that acts as the ROM.
