PC10- cant get the "reset" button to work

Hi Guys,

I have a2 x PC10 units on hand. I wired 2 of them up and all the buttons works on both except the "reset" button. I swapped 3 known good boards and it made no difference. Button are wired as follows. There are 3 leads on the small switches- 2 leads are close to one another. I wired the color wire to the middle of the switch and the ground to the end of the switch by itself opposite the 2 leads that are close to each other. I verified that the 2 wires to the board are good. I also plugged in another ground to the switch and it made no difference. I even plugged the 2 to each other and nothing. If I do this with any switch it always works. Hence the switch is not the problem. Maybe there is a dip setting for this? Not sure as 8 of the 16 dips are not labeled on the PC10 manual. I will even run a small wire if need be. Anyone know how to resolve this.....

Any ideas?? :confused:

Thanks guys
 
Mine does the same thing. You have to pretty much hold down the game select and start buttons (menu) to get it to "reset" and take you back to the game select screen.

Hold them for about half a second.

So, if you wanted to then fix your reset buttons, you could wire two diodes and wires from those buttons to your reset button. That way, holding down the reset button for a moment would then get you to the menu screen. It's a known glitch.
 
Thanks it worked. Damn I thought it was a board issue but 3 boards made my ? myself.

Appreciate the response !!
 
Hi there! My PC-10 did the same thing. The reset button worked then it stopped one day. This was after a rom swap. I traced the reset wire from the button to the board connector (should be pink). I used my meter and checked the continuity. The wire was fine and the button checked out as well. While the above mentioned trick worked it always bugged me that things didn't work like they were supposed to. So I tackled it again and it turned out that the reset wire pin wasn't fully seated into the board connector. So basically the switch signal wasn't making contact with the board contact. It is usually the simplest solutions that are overlooked. I pushed it in further and it was fixed. It has been awhile but if I remember right the wire is the very first wire on the top connector. It is prone to excessive wiggle being exposed on the end (from rom swaps). I have also heard a rumor that some of the earlier PC-10 single monitor boards had a flaw in them where the reset button didn't work. That is where the game select/start button trick came from. Since you have tried a few different boards, I am thinking that this might be your problem. Give this a try. Let me know how it turns out. I threw this at you in case you are like me and the little things annoy you.

Thanks for the tip Chris. I checked again and all the wiring is factory tight even on the connectors to the pcb. Looks like its the standard board flaw.

It isn't a board flaw. The older PC boards will not reset using the "reset button" in free play mode. The reset button will work when the game is in "regular credit" mode, but when set to free play the "channel select" and "enter" buttons are used to exit to the game select screen. This was later corrected.
