It is sadly true that many of the old-line Rt 128 companies are
gone... DEC, Data General, GR, Sensitive Instruments, Clevite,
Transitron, probably others.

Have others popped up to take their place?

Why sure. Can you red Chinese tech manuals?

Funny how my Made-In-China keyboard with its @#%^$}# sticky "a" key

Ah, Bruker, my arch-enemy. I make the gradient drivers and temperature
controllers for Varian. I've also had bad experiences with Bruker AXS
in Madison. They both seem to be very NIH and very PhD oriented, so
they're hard to deal with and especially sell to.
