Re: Non-working Commodore PET 3016
Yes, the ability to 'pan' left and right can be useful.
I'm going to let Mark go with this for a while so you don't get conflicting instructions sending you in two directions at once.
In the meantime a little exercise for you:
Taking your screen shot in #680,
Can you say, roughly...
How many milliseconds there are between the falling edge of the first _CE pulse and the falling edge of the second _CE pulse?
How long (In milliseconds) is one _CE pulse?
Assuming the low edges of the _CE pulses are at 0V, what voltage is the _CE line at when it is NOT low?
(With the scope settings as they were, each horizontal division is 50mS: Each vertical division is 2V).
