Unfortunately, all of this depends on what things really cost, and when they cost what they cost, and at what volumes are those costs. I suspect it maybe be a while till the 68882 costs $50, but then I haven't bought any lately, so I could be wrong. It's often very hard to get real numbers. >the 68030 system can use.

Mark Linimon suggested a paraphrase of the Russian roulette analogy especially appropiate to RISC: Russian roulette in the delay slot. -- -john mashey DISCLAIMER: UUCP: {ames,decwrl,prls,pyramid}!mips!mash OR mash@mips.com DDD: 408-991-0253 or 408-720-1700, x253 USPS: MIPS Computer Systems, 930 E.
