- He was probably the same DEC marketing dwid who said last year that
- HP was "up against the ceiling" in performance. We "just took old
- technology and pushed it to the limit." Well, it worked last year and
- it worked this year. Anybody want to bet against us next year?
-
- When are marketeers going to stop projecting the limits of what engineers
- can do, and just let us get on with doing it? Get over it, people. Stop
- predicting who's out of gas and look forward.

- Surely. Or not. If it's the right thing to do, you can bet we'll do

- You did an excellent job of explaining why the junior architects' club
- doesn't design VLSI chips. They can sit back and handwave all they
- want, but the proof is in the product.
-
- Can't anyone understand that the 21064 and the 7100 aren't blazing fast
- because the architectures are great, but because the engineering was
- great? I'm sure the Alpha design team could have built a MIPS
- architecture chip that performed just about as well as Alpha if it
- suited their purposes.
