Interesting you should mention PMI. I worked for PMI 1978-1982 as a design
engineer, so I've got a databook from that period. I built my modular synth
when I was at PMI.
PMI was bought out by Analog Devices, and the old PMI plant in Santa Clara
is still there, except the sign says Analog Devices now. The Analog Devices
website lists most of the devices offered by PMI, with datasheets.
Ever hear of the OP-27 (low noise, high speed, hi preceision opamp)? I was
a co-designer on that, and the metal mask still has my initials on it. I
use OP-27's instead of 741's because I had 150 or so of them from a
pre-production run (only about 50 left).
