What’s a CRO ?
Do you know where we can find some good schematics about the 67 ?
Looks like there is a loro less documentation compared to what’s available for the HP65
We’ll keep posting our results !

Sorry, a habit - Cathode Ray Oscilloscope - or these days just an oscilloscope. I thought you had a pico-scope which will help. Some of the wave forms shown in the 97 service document may serve as a guide.

My web site has some schematics that I put together in pdf format...
