I never used the tool, I just used a small jewelers type screwdriver and it worked fine.

If they are the same as the IDC connectors in my system80 game then yes. I didn't have much problem at all, could just be dumb luck but it went easy for me. I didn't have to modify my screwdriver or anything. Mabe mine were worn the the point they were already getting loose in the housing, who knows.

You know you can re-tin those connector edges and it makes a hell of a difference in how things work (reliability wise).

Those look just like mine. I think they are IDC card connectors. They take .156 molex replacement pins if I recall correctly, is that what you had to order??? IDC just refers to the type of connection made with the wires not the board edges. I may be wrong so please don't get offended, I'm not implying your wrong just trying to help.

You my be correct, I'm no expert by any means either and I too use clay's guides but was not aware of the fact that IDC's were not used until system80's which is what I have (Star Race that by the way I just got back up and working perfectly) I only mentioned not taking offense because some get really aggitated on here if you mention much counter to what they say. Good luck you'll get it done I'm sure.

I need to pick your brain Examiner!!!
