Quoted from slochar:
What game I'm assuming a Gottlieb if they're edge connectors..... toss out what I said and go with the other poster that said you need the extractor tool.
If they're not edge I'd either go with a 20 cut down and sub 2 smaller ones for the 24 but like I said... guessing they're edge connectors I don't think anyone else ever used more than a 20 regular? (Bally and Stern with the displays and rectifier board)
They are edge connectors, its a 19 pin edge connector I'm dealing with now. I have the extractor tool, but the procedure is to typically depress the tang and then pull the wire to pull out the pin... problem is the wire is no longer attached so its quite difficult to actually get that pin out, plus its IDC so its wedged in there pretty good and although I've read a few posts that indicate you can swap them with regular crimp pins, I'm not convinced these things are meant to be removed.
