Joost RekveldYesterday I figured out how to automate entering text into a Tektronix text generator from the early 1970s, so that I can animate it.
A quirky protocol that is sort of documented except the exceptions...
Slowly wrapping my mind around how to work with text on an analogue XY-display.

Today I figured out that I need this strange kludge to permute three pins of this IC and change the order of events (inside an analogue Tektronix 7704A oscilloscope).

I certainly did not expect that all those 228 buttons from the 1970s would just still work 50 years later.
Szymon BęczkowskiAnyone has experience with Keithley 2461 SMU? When I initialize the digitizer, the trigger model execution waits for the measurement to complete. Instead, I would like it to start collecting data and instantly start the pulse generator.
Today I repaired this Tektronix 7M13 plugin from 1976.
In preparation of a small side-project I bought some vintage Tektronix analogue electronic plugins, for the first time in ages. I'm always curious to find out about previous owners; in this case the innocuous label N65236 stands for the 'Space and Naval Warfare Systems Center Atlantic' in Charleston, South Carolina.

Spent way too much time trying to get this horizontal amplifier not to be biased and failing miserably. All components seem to be fine but the whole is not. Argh.
The Tektronix 7704A oscilloscope is the most modular analogue oscilloscope I know: not only does it have space for four amplifier and trigger plugins, but even the 'display unit' holding the CRT can be swapped for another one.
After several years of owning a spare 'display unit' I finally have a project where this strange feature may turn out to be actually useful. But first these machines need some maintenance and repair.
Consulting the old manuals researching the technical feasibility of a smallish spin-off project..
