Same results!Can you do the same for the three pins of the other potentiometer please (R333)?
Hi Dave, i taken 0V ref. from this point in picture!Just out of interest, where was your 0V reference taken from when you were probing the two potentiometers?
Yes !I take it that you are referring to the large braided cable?
Yes image moving left and right, no widening and shrinkings the whole image moving left and right
Yes Dave, unfortunately i don't have this diagnostic cart...but maybe it's possible create one....if i found correct firmware....That is very useful!
However, this waveform will be obtained when only a certain program is running in the Vectrex. There is a “diagnostic/test” cartridge - which I assume you don’t have?
Under what conditions were those traces taken? If you have the necessary firmware they will be really helpful!

This is document:What dies the document say where you found the oscilloscope traces?
