Tony,
Do you know anything about the Tektronix 4096 plotters? I saw one the
other day. I started to buy it to add to my 4051 (it has the GP-IB interface).

I have a feeling you would be the only person within our list and perhaps
most other computer collectors who has a PERQ. I never seen one, know very
That depends on the group of collectors. There are a number of serious
'PERQ-fantics' around, but for some reason, not many are on this list.

Never heard of a TEK 31 myself 'till then.
When I saw it I figured I had
better grab it since I felt it was a rather rare thing even back then. I
don't recall finding anything on it in my collection of older TEK catalogs.
There was an article on them (21 and 31) in Tekscope when they came out.
Alas I didn't rescue the pile of Tekscopes that I read that in - some
other collector got them. I got the HP journals (including the one on the
9100 ;-))

Was the TEK 21 you mentioned above earlier than
the TEK 31 or just
different in other ways?
It came out at the same time. It was a simpler machine, I was going to
say non-programmable, apart from the fact that I have a part number for
an operating/programming manual for it. Maybe it didn't have all the
'scientific' functions.
However, I do have the service manual for the 4661 plotter that goes with
these machines. I'm not getting rid of it - I have a 4662 plotter and
much of the mechanics is the same - but I can provide info from it.
Are these plotters similar in concept to the 4331 printers? Used a special
thermal paper I think. Such printer could hang off my TEK 4015-1 graphics
No, they're actual flatbed pen plotters.
terminal and print directly from the screen. The
401x series had an X-Y
analog plotter output for actual plotting.
The 4662 is a normal (although not HPGL) GPIB or RS232 interfaced
plotter. It was used with the 405x series amongst other things. The 4661
was a similar unit with a 21/31 calculator interface (and totally
different electronics).
Here is the pinout of the calculator I/O connector.
Evidently in that service manual it mentions the plotter could hang off a
TEK 31, true? If so, then this is indeed the connector pinout for my TEK
Yes. That's why I mentioned it. That should be the pinout of the
connector on the back of the 31. Alas I don't have the 'interface
specification' (I can find the Tek part number if you want to try to
obtain it) for this machine.
I have an
incomplete (still missing the lights-and-switches board) Nova
1210 here.
Hmmm, I have to check but I *think* there is something about 1210's in the
DG Nova printset I have. I know there's schemas for the 1200 and 800
I've got the schematics of the CPU + frontpanel. It's just a matter of
finding time to make a PCB, etc...
