High performance coprocessor boards of the 80s and 90s - was Re: SGI ONYX

[Guy Sotomayor]

There was also an 80286 coprocessor board for various VAXen.

Let’s not also forget the various 370 and 390 co-processor boards that could be
put into PC’s at various times to allow one to turn the PC into a small mainframe
capable of running mainframe software (including the OS).
