Hi guys,
A few of you might remember the IBM LPFK bulk-order a couple of years back,
and the ensuing chaos of figuring out the control protocol (which was
eventually resolved when Michael Brutman found some old IBM protocol docs
which covered the LPFK).
Some of the long-time VLSI design folks I work with still prefer these for
layout entry. I've heard them referred to as "bump buttons", probably
because of the way they're mapped into some of our internal layout tools.
