Well at last count, my Amiga has 3 CPU's and 6 coprocessors. Yes, they run simultainiously. Oh wait, you mean multi-processing. Well, when UNIX does this, with three disparete environments, let me know! No problem multi-tasking. Just have to fight for 2 Ethernet addresses for bandwidth. -- Work: Computer Consoles Inc.

He probably isn't going to count the keyboard microprocessor as a cpu. He probably wants 25 68020's or 10 Sun 4's. He probably wants a BBN Butterfly. *I'd* like a BBN Butterfly too. I think it's safe to assume that pretty much everybody reading this would like a BBN Butterfly. But I'll settle for the most colors for the least price. -- "He tried to do his best, but he could not" richard@gryphon.CTS.COM {ihnp4!scgvaxd!cadovax, rutgers!marque, codas!ddsw1} gryphon!richard

Hmmm, well Sequent does run multiple processes on multiple processors and unix works fine. Alliant doesn't seem to have a problem mixing unix up with CE's and IOP's. I believe the IOPs are 68020's. CDC 825 (don't know if this environment is still for sale) ran NOS, NOS/VE, and an unix sys V clone all at once. Note that the processor was switching instruction sets and memory managment schemes in mid stream. Quite a nice idea, and it worked. The hardware was great, but the software was a different matter entirely. I remember one of the engineers looking at incredously when I asked for wild cards in the SCL for NOS/VE. The Amy is nice technology for personal computers, but it is by no means the forfront of technology today.

For $1000.00 it is... ---------------------------------- On a related note. Remeber that smee fella in the UK that started this heinous "multitasking - a nightmare" bull ? Well, he and I have been talking, ant what it really comes down to is he thinks multitasking is pretty neat, and thinks it is usefull for your average joe, but when one process steps on another all the benefits are negated. Can you say 68020 ? Can you say MMU ? -- "My life is changing in so many ways, I don't know who to trust any more" richard@gryphon.CTS.COM {ihnp4!scgvaxd!cadovax, rutgers!marque, codas!ddsw1} gryphon!richard
