>NeXT tried to get its own NeXT RISC workstation to market (chased a chimera) and looked at Motorola 88000 and PowerPC
Jobs made a huge mistake by going with the 68K in the first place. DEC would prove just a few months after NeXT's October 1988 launch the viability of a MIPS-powered workstation.
Even better, in the long term, would have been to go with the 80386.
In fairness, I think it wasn't obvious that Motorola would run into so much trouble with the 68k line, or that 80386 would be the far-away winner. Sun and many others were betting on 68k, too.
