Sorry guys if this is obvious, I did a search and didn't see anything obvious when I put in "ESC and TAB IPAC"...
When using one of Andy's 54pin IPAC's, how does one wire up the ESC and TAB keys, both very useful for MAME.......I don't see pinouts for those keys....I'll hit the IPAC site now but if anyone had a quick answer.
Also, there are two GND screws on the IPAC board...uh, is it an "either or" situation......use either one, or use both or...
