Re: Just got myself a commodore pet setup but not working
The signals are noisy due to using the case as an earth but they look like they have the correct activity. It would be better to use 0 v reference from the ICs where you are measuring outputs. Usually pin 7 on 14 pin ICs or pin 8 on 16 pin, but check schematic or IC pinout in datasheet to confirm.
Were you able to see an orange glow on the back of the CRT?
