What the hell are you talking about? The "leaps" in both product lines were exactly the same (on-board FPU, cache, speed improvements). Why do all of you Amigoids have it etched upon your brains that Motorola is, was, and always will be "clearly superior"? The difference in the technology has been slight ever since the '030/'386 (5 years now), especially if you're trying to look at the "big picture". Sure, Amiga and IBM clone technologies are pretty far apart, but their respective processors really aren't. > >Intel has been pushing >the idea of using an i860 as a coprocessor, depite the fact it's not all that >well suited to the job (thought the new one they just announced is better), >simply because Intel would really, really, really, really like to get two of >their expensive chips into every high end PClone, rather than just one. > Sorry Dave. The i860 is EXTREMELY well-suited to the job of a coprocessor, for graphics or floating point. It isn't that well-suited to the job of a CPU, however, because its integer unit is somewhat lacking, although a few manufacturers did it anyway. We'll have to see what happens with the new i860XL. You're right about Intel's marketing games, however. I cannot believe the ride they're offering customers now, with their 486SX/487SX processors. OK, I can accept the idea of the 486SX, for those people who don't need the FPU or cannot afford the full 486. But pricing the 487SX as a coprocessor (big bucks) is really sleazy, considering it is nothing more than a full 486 repackaged with an extra pin that turns off the 486SX. > >And the 680x0 environment is a >heck of a lot easier to emulate in software than the brain dead combination >of MS-DOS and a '486 type CPU. > MS-DOS is truly "braindead", but the '486 is not. In fact, it is an excellent 32-bit processor with a built in FPU, MMU, and a 64-terabyte virtual memory space. Show me how the '486 is braindead, Dave. Show me that you can do more, Dave, than post the same old ignorant Amigoid ramblings full of BS phrases like "braindead". > >Dave Haynie Commodore-Amiga (Amiga 3000) "The Crew That Never Rests" > {uunet|pyramid|rutgers}!cbmvax!daveh PLINK: hazy BIX: hazy > -- +-------------------+----------------------+---------------------------------+ | JERRY J.
