Just to make sure there's no mis-impression: a) R6000s do not contribute to sales of Prestone or any other coolant; they are air-cooled, and they are VLSI ECL, not massive boards full of ECL gate arrays. b) However, as I've said before, no one is likely to build desktops from these things: even if aircooled, they are hot, and a desktop would turn into new kind of product: above-the-desk, as it floats on its fans. So please stop talking about R6000-based desktops. c) However, it is perfectly predictable that there will be CMOS-based desktops with the same CPU performance, within a few years. Whether you call these PCs or workstations doesn't matter much. -- -john mashey DISCLAIMER: <generic disclaimer, I speak for me only, etc> 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.

Sure it does. If you call it a PC you have to produce a brain-damaged
proprietary operating system to run on it.

Whether you call these PCs or workstations doesn't matter much. John, I think that you are over estimating the time period in which a Killer Micro is eaten by its children by about a factor of two. What did the baby Killer Micro say to its mom at birth? "Look ma!, no fans!" brooks@maddog.llnl.gov, brooks@maddog.uucp

Whether you call these PCs or workstations doesn't matter much. But doesn't CMOS get just as hot when you start clocking it at ECL speeds. Or if not as hot, close enough to have serious power and cooling problems. Gerry Gleason
