From the project

A hardware fork of 68k nano, Matt Sarnoff's minimal single-board Motorola 68000 computer, adapted to use a PGA-68 packaged CPU (MC68HC000RC) instead of the original DIP-64, and re-laid-out on a 4-layer board.

A hardware fork of 68k nano, Matt Sarnoff's minimal single-board Motorola 68000 computer, adapted to use a PGA-68 packaged CPU (MC68HC000RC) instead of the original DIP-64, and re-laid-out on a 4-layer board.

The electrical design — the memory map, glue logic, RAM/ROM/UART, the ROM firmware, and all software — is Matt Sarnoff's original work, used here under the BSD-3-Clause license (see below). This fork only changes the CPU package and the physical board layout; the schematic netlist is unchanged.
