Hitachi's SH series were supposedly named that because they were "super hot". Their marketing department didn't manage to propagate that interpretation but I liked the architecture.

It was always amusing to visit Sega HQ back in those days and see how all-in they were on Hitachi: from the Hitachi elevator in the building to the conference rooms with Hitachi OHP, Hitachi wall clock, Hitachi conference table, Hitachi pens, hitachi computers and of course Hitachi chips... Those huge conglomerates (Keiretsu) are crazy!
