Linux developers have been trimming the fluff in recent years, removing support for older processors that hardly anyone uses with a modern kernel anymore. With that said, it’s possible to run the latest kernel on some truly old metal. As a case in point, [Colin Maykish] just got it going on a Motorola 68008!The rig in question is a Mackerel-68k—a homebrew single-board computer built around Motorola’s famous 68000 CPU line. This version in particular is running a 68008 rated at 8 MHz, though it’s overclocked to 14 MHz for a little more pep, and has just 3.5 MB of RAM. Despite these limitations, the board can run the mainline v7.1-rc6 kernel, booting into userspace and providing a very minimalistic BusyBox shell. Booting is slow, and doing much more than that is impossible without running out of RAM, but it’s an impressive feat nonetheless. [Colin] has also had the 68010 and 68030 chips running the kernel, too.We’ve previously discussed efforts to bring Linux into the future while leaving old chips behind. Video after the break.
