atari-dna Posted October 24, 2018 Share Posted October 24, 2018 (edited) No function on the switch. Ive replaced C3 1uF to a 10uF. The manual operation is fine, but there is no reset triggered when activating the switch. I welcome all input on diagnosing this problem.

Hannacek Posted October 24, 2018 Share Posted October 24, 2018 Did you test the switch for continuity with a multimeter? A broken trace would be the likely problem. Quote Link to comment Share on other sites More sharing options...

I'll get the meter on it this evening. This is SPST, correct? Doesn't the reset switch tie directly to the reset line on the Z80 ? Quote Link to comment Share on other sites More sharing options...
Hannacek Posted October 24, 2018 Share Posted October 24, 2018 It is a momentary switch. I would assume it connects a signal to ground (the signal is probably the reset line on the Z80 or another chip). You could first connect a paperclip or something to the two leads on the board to see it it resets.It is just a simple 2 sided board with no layers, so you can just follow the traces on the bottom and top of the board to see where it connects. 1 Quote Link to comment Share on other sites More sharing options...
