Here is some detail on the control panel for the arcade. I cut two pieces of wood to the dimensions of the original panel. A bit tricky for a table saw noob as there were quite a few angles but with the help of a protractor and some tests cuts everything came out as expected.
I designed the panel in Visio using the button, joystick and trackball stencils available on this site. I then printed it out full scale and taped the pages together. I then taped it to the top of the panel to drill pilot holes for the placement of the controls. I had to router out the bottom of the panel for the trackball but I also routed out a bit for each of the joysticks so they would be a bit longer (definitely needed for the J-stick as all are bottom mounted. Then using hole saws I drilled the openings.
The design is basically what I was using for my test panel with small adjustments for width and to add the trackball.
The equipment is:
Happ Comp Joys for P1 and P2
J-Stick for the 4-way
X-Arcade Trackball
I went with 7 buttons for 1 and 2, 2 at the 4 way, P1/2 start and coin and Esc and Pause admin buttons
The buttons and joys will be connected through and IPAC
