Well, the VAX was there before any of these, but I wouldn't call that a "personal machine." I suppose the argument could be made that the 68000 was first, as both it and MIPS ended up in gaming consoles (Sega Genesis vs. Sony PS2 and Nintendo 64). However, MIPS eventually scaled to 64-bit, was well-known and heavily exploited in supercomputing applications, and was used to produce the film Jurassic Park. The 68000 had a far dimmer future. Yes, the x86 line did supplant them all, but only with AMD's help. Had Itanium been Intel's final answer, MIPS might be much stronger today.
