Neat, hadn't seen these Comdynas before you and Dwight mentioned them.
One issue is this Tyrotek doesn't have an automatic cycling mode, it looks like such
was another option. The control states are Reset (initial conditions), Operate
(calculate)
and Hold, no "Repeat-Op". So to use it with a scope I would have to build a
cycling unit, (possible, the connections are there to do it, but
something more to do), or, I guess, build oscillators as part of the program.
I can almost trace out the program from your photo, but do you have it written
or diagrammed in some format that could be easily communicated? I take it there
are back-panel connections to the scope in the setup you show, I see only
the one feed to the scope.
What can be done with it when it's
functioning will be another question.
The only built-in 'output' device is a solitary analog meter. I have my eye on
an HP analog chart recorder buried at the radio museum, to use as an output
recorder, but I expect it has ink issues in the way of getting it going.
One output device to use is an oscilloscope.
Here's a photo of my Comdyna generating a double-well
chaos equation:
