Ever use the WD2511?  True, it's only a microcoded controller, but so full
of bugs that some X.25 networks won't certify any boxes with one in it!

And, if they couldn't get it right the first time, then they came out with
the WD2511A, the WD2512, and then the WD2512A.  It's been 5 years, and we
still don't have a bug free chip.

Intel may not be the best at releasing bug free silicon, but there are 
certainly worse vendors out there.
