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).
Also got a stack of circuit boards from an Olivetti Programma 101
(early 60s) as well as the general reference manual and some programming
sheets - unfortunately the machine itself was "taken apart" many years ago
and this is all that remains - the boards are very interesting and worth
keeping on their own, as they utilize discrete resistor/transistor logic
modules. However, if someone on this list has a Programma 101 in need of
parts, I would rather see them used to heal a whole machine instead of
sitting on my shelf as curiosities.
Regards,
Dave
PS: Also picked up a "MicroWat" - 6809 based computer built by the University
of Waterloo in Canada - if anyone has info please contact me.

I just found a tape (printed paper) of my program for printing a random
toss of the dice, something I banged into an Olivetti 101 back in about
1977 or so. It's huge.
It was in the same box as some six rolls of 1" 8-column punched paper
tape, canary yellow, from the ASR-33 I used to use to write programs on the
TSS/8 system in high school, same era as above. I have no idea what the
programs were for. I might not have punched a people-readable header, or I
might have rolled them end-out for some long forgotten reason.
Looking at the printouts that were with them, it doesn't seem to be a huge
loss. I was a really awful programmer in high school.

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.

Hi Dave,
Rick Bensene seems to be the expert on the Tektronix 31s. I think he has
a section on his website about them. He used to work for Tektronix. FWIW I
have three Tek 31s NIB! Had a fourth one labeled as a (mumble) Survey
Calculator but I got rid of it.
OH I think Sellam had some kind of docs for the T31s too but I doubt he's
been able to find them.

I've got the manual and I may even know where the box is that contains it.
I've promised Dave I'll look for it over the weekend.
Where the hell did you find 3 Tek 31's NIB? Nice score!

Where the hell did you find 3 Tek 31's NIB? Nice score! from used to work for Tektronix and he brought them
here when Tektronix
transferred him here from Oregon years ago but then never used
them. They
had a few papers with them but the bugs had pretty well eaten them up. I
suspect he had the manuals for them but had lost them or tossed them years
ago.
