You know that DEC's been discontinued (bought by Compaq)? I read that
Compaq is selling (sold?) the Alpha to Intel right now.
um = micrometer (millionth of a meter) which is the track width of the
microprocessor. I thought 0.15um was state of the art, but it seems that
it's now 0.13um. 0.35um is older technology.

Steven

Nice observations. The alpha is gone now? When did DEC
discontinue it? Lastly in the measurement what does
"um" stand for? Thanks
