Sega Dreamcast and T2/Linux
When released around 1999 the Sega Dreamcast was considered to be quite ahead of the competing video game consoles at that time.
The console featured a 200MHz SH-4 (SuperH 4) 32-bit RISC CPU, with 128-bit SIMD FPU, PowerVR2 as 3D graphic accelerator with 16 MB main memory and 8 MB video memory.
As outside gaming machines and automtive markets the SuperH chips are sort of rare, the Sega Dreamcast served as testbed to develop and test the SuperH support in T2.
Quirks and notes
Due to the copy protection of games the systems only boots from specially blessed ISOs.
