Not all minis came from the States :-) One of my favourite non-mainstream families is the Philips P800 series. It's a 16 bit machine with 16 registers (0 is the program counter and 15 is the stack pointer, rest are mostly general purpose) and separate I/O instructions (not memory-mapped I/O). There were several models with various implementations of the architecture, including
P850 (TTL, hardwired not microcoded) P855, P852, P856, P857, P860 (TTL, microcoded) P851 (Custom bitslice ICs, microcoded) P854 (AM2900 bitslice, microcoded) P853 I think (Single chip) No, I don't have all of those... -tony
