I do. It's basicly a card cage that you buy and then stuff with various optional IO
cards. There are a lot of different cards for it and they include things like digital
inputs, digital output, analog input and output cards, counters, programmable frequency
and signal type (square wave, sine wave, etc etc) output cards, relay closure cards and
many others. The 6942 is much more desirable than the older 6940 since it has a hP-IB
port built-in and can be directly controlled by HP-IB. The 6940 used a parallel port
interface but you could buy an optional HP-IB interface (separate unit).

The systems are HP3350 Laboratory Automation
Systems, each consists of:
HP-1000 F Series Computer,
HP 12990B Memory Extender
HP 12979B 1/O Extender
HP 7970E Tape Drive
2xHP 7925 Disk Drives
I have a gadget in the garage that I think has some connection
with these. It's an HP 6942A Multiprogrammer, and it's mounted in
a rack-style case just like those shown in the photos of this HP
gear. Can anyone use it? Does anyone know what is does?
Located in the frozen North of Bristol, UK.
