From the project

A series of single-board Motorola 68k computers with support for modern Linux

Mackerel 68k is a family of homebrew single-board computers built around the Motorola 68000 line of processors plus a from-scratch effort to run mainline Linux on each one.

The project works its way up the 68k family one chip at a time, from the 68008 to the 68040. Each new board adds capability: more memory, faster CPUs, an FPU, an MMU, and richer peripherals. But the throughline is software - every Mackerel runs the latest mainline Linux kernel, from a tiny NOMMU uClinux shell on the 68008 up to a full MMU + hardware-FPU install on the 68030.
