Heh, M68k was shipping about 9 months after intels 8086, aka the year 1979. And it was probably one of the most powerful CPU's on the normal consumer market untill the 80386 with "tru" 32bit came out in 1988, 9 years(!) later.
By "normal consumer" I don't mean sparc and the Dec alpha and silicon graphics workstation, they were more for a special type market. Unix typically didn't run on home computers either. Not untill Amiga..... :P
