My friend had an Acorn RiscPC with some form of pentium card expansion. It was pretty cool, the display was mapped into a window on RiscOS. I remember us getting quake running on it.
Those RiscPC processor cards were the real deal - I'm wasnt aware you could get Pentium versions but you could certainly buy 486DX 100mhz cards which could be upgraded with an AMD 5x86 133mhz.
