IIRC, Stratus was M68K (like 12 per cpu board organized into 3 logical cpu's for fault checking)

The OG Stratus FT was mc68k; what a beast. They moved to Intel i860 in the early 90s (XA series...I had a processor board from one hanging in my conference room back in the day), then HP-PA (Continuum series) in the 2000s and these days it's apparently virtualized on x86. Still very popular in the credit card processing world.

		That's where I came across them in around 03/04, though the company was moving away from them at the time. Two intel processors somehow kept in lockstep, allowing either one (or its RAM) to fail and be replaced with no interruption to the system.
