The big question is 'what is the pulse used for?' and when is it triggered?
What are /A1, /A2, and B hooked to? (pins 3, 4 & 5 respectively.)
Hmmmm... it would seem /A1 and /A2 are grounded, while B is not connected? Does that mean it is always triggered, or what?
What are outputs Q & /Q hooked to? (pins 6 for a high pulse & pin 1 for a low pulse)
Q is not connected, /Q goes to pin 3 of a 74LS74. That's all I can find out now, the number of traces on this board is somewhat intimidating, and there are lots and lots of trough-connections that make it hard to follow them. So I don't think I'll make a schematic just to solve the "mystery pot" thing.
Thanks a lot for your help so far. -- Linards Ticmanis The Master said, "The business of laying on the colors follows the preparation of the plain ground."
