Dev ports Linux to Atari’s notorious Jaguar console from 1993 — the first 64-bit console features 2MB of RAM, 13.3 MHz CPU, and Tom and Jerry co-processors; the Jag was notoriously difficult to program and flopped

A Spanish systems software developer has ported Linux to the Atari Jaguar console. To succeed at the task, cakehonolulu had to overcome severe memory limits, the lack of a memory management unit (MMU), and face off against a handful of unusual hardware quirks. A blog post from the dev tells us about the work to port Linux to this ill-fated 1993-launched flop, and happily ends in evidence that a working Linux kernel and BusyBox command line shell can be booted on the old Jag. Now Linux runs on both your cherished real hardware via cartridge, or in a Jaguar emulator.

Anyone wishing to port Linux to the Atari Jaguar would face numerous constraints due to the hardware. One of the first hurdles successfully leaped by cakehonolulu was the CPU used. Atari’s system designers architected the Jag using a Motorola 68000 CPU, which was already pretty old at the time, but a moderately fast 13.3 MHz version was selected. Though the gaming prowess of the console was lifted by custom co-processors dubbed Tom & Jerry, some games didn’t make much use of this graphics and DSP acceleration, as it was notoriously difficult to tap into.
