> I have to assume they reached that solution after exhausting every other option I assume that the 68000 was so powerful for its price (probably much cheaper than the existing mainframe CPUs) that it made this a viable solution. Or maybe the company had promised their customers a 68k-based Unix system (with the 68451 MMU) and the 68010 was delayed or too expensive and they had to find a quick solution? (I have no idea) Btw, I was probably wrong about Sun being the company behind this. Apollo and MassComp have been mentioned in mailing lists.
