First, sorry about the annoying format...I am just getting used to this editor. 
Anyway, I am a dedicated IBM user only when I can not get my hands on a DEC
APX-series machine.  Let's face it, Intel has demonstrated once again their
slipshod approach to engineering and pseudo-foxes.  I realize the Alpha
machines cost a lot more, but maybe you get what you pay for...90 mHz with
errors in the important stuff (how do you miss such a significant thing as a
buggy fpu?!), or >200 mHz (with BIG buses!) and real engineering.

Sorry to ramble...I am kinda fond of the guys at DEC...
