No. The 60 was grossly inferior to the 70 in most ways: hardware address space, integer processing speed, I/O bandwidth, etc. Its optional floating-point hardware was (I think) the same as the 70's. Otherwise, it was a piece of junk. There has been persistent speculation that the original 60 was much faster than the one that was finally released to the customers; it is hard to see how it could possibly deserve that model number otherwise. A well-equipped 45 was a better machine, and the 55 could run rings around it. The (slightly later) 44 was superior to the 60 in every way except floating-point, where the 44's lousy FPP (a slight variant of the 34 FPP) held it back. -- "Mir" means "peace", as in | Henry Spencer @ U of Toronto Zoology "the war is over; we've won". | {allegra,ihnp4,decvax,utai}!utzoo!henry You may think you won a war, but you keep posting irrelevant messages to comp.os.minix Don't you know how to post to the correct newsgroup?
