Dusting off Dreamcast Linux

A keyboard, mouse, a NIC, VGA output, 16MB of RAM and a whole gig (you wish) of read-only optical drive space with a 200MHz Hitachi SuperH SH-4 CPU faulting its paltry 8K of I-cache and 16K of D-cache non-stop. Now freshly refurbished, its cooling fan runs louder than my Power Mac Quad G5 at idle and the drive makes more disk seeking noise than when I can't find a lost floppy. And since the buzzword with Linux distros today is immutability, what could be more immutable than an ephemeral, desperately undersized RAM disk overlaid on a live CD?

i want a DreamCast.
