I gave up trying to insert pics in the middle of the post...

Controls include an 8-way Happ w/ leafs and a 2 1/4" Wico trackball. Admin buttons are
Exit (esc) and Pause (P), plus shifted Tab, Enter, L Shift and F7. The left mouse button
(from the minipac) is wired into the credit button on the front of the cab. At first I
had it shared w/ button 1 but mame/mamewah were locking up so I switched it to the 2P
start, but that didn't work in mamewah because that button brings up the menu and it
didn't like getting a mouse click at the same time. No problems yet where it is now. If that doesn't work I'll just give up use the real mouse in the back.
Software is Windows 98SE, MAME .61 and MameWah, with a Mr. Salty layout.
I used a Mini-PAC (remember the deal Andy had for BYOACers a while back?), plugged into
USB so I could have a trackball. Note: I never figured out how to program the mini-PAC
thru the USB port; kept getting errors, and not the usual "time out" error. I ended up
doing it with the PS2 connection without a problem.
