Hi Guys,
Just picked up an Tektronix Model 31 desktop calculator. This is a
fairly old (early 70s) desktop programmable with built in tape storage
and printer.
Looking for information/documenation on it - all I got was the bare
unit (which looks to be in good shape).
It's not much, but somewhere I have the service manual for the 4661
plotter that was used with this machine. I think at least I could get you
a pinout of the I/O connector if that's of any interest.
