Bit more done today...
I wired up the control panel (now with a satin RAL9002 top coat), and put it on the cabinet to get an idea how it looks:

I'm considering putting a clear, gloss lacquer layer on it. Not sure at the moment.
This is cool (although looks a bit messy)... I got a PC with a j-pac and an i-pac together.... j-pac does the usual jamma interface and p1&2. i-pac is hooked up to the two 9-pin AMP break out cables for p3&4. Bottom right is the sound amp (tapping 12v off the jamma):

It's quick to plug in / unplug.... and I can use it until I get some 4p boards
It fits into the PCB area really nicely (note: the rust will be gone in a future update!):
I tested it all out with a bit of Golden Axe: TRODA - too late at night to wake the kids up and test all 4 players at once... but will try that out tomorrow

. Ignore the black and white header art... Still waiting for the colour one to come back from the printers.
