I summed up my problem once before, but I will try and re-explain it:

I didn't want to modify the cabinet externally, so I put credit switches (leaf
style) behind the coin eject buttons on each coin door on each side. So for a
player to join, they would simply have to press a coin eject button.

The problem is that Sega's coining timing is sooo picky on E4, that you have to
time it just right. While I have picked up on this myself, trying to explain
it to a bunch of people (who've usually been drinking, which doesn't help any
:-)) isn't always easy, and so there is 3 other people punching in the coin
eject buttons. Whenever one of them get's it incorrectly, it temporarily locks
up the CPU, and anyone else trying to credit during that time fails and their
attempts are voided. So you got a bunch of people screwing up, which locks out
everyone else, and then, well, it's a mess. Rick Schieve's E4 set up also
experiences the same problem as mine.

If the crediting logic were less pickly, likely any brief contact would result
in a successfuly credit, which I think even my friends may be able to achieve
:-).

If you stop by during Pinball Expo 99, you'll understand what I mean.

If you're coming Wednesday, you'll probably want to go Rick Schieve's pinball
party instead. He always has it on the Wednesday before the expo.

Name rings a bell, but I don't know him personally.
