I went with some HAPP controls on eBay. I purchased them before your response and was relieved I purchased Happ competition sticks and happ buttons. I ended up getting 16 buttons, 2 joysticks, and a Xin Mo joystick encoder. I was unaware of this being a joystick encoder (expected keyboard) but more on that later.
I received the controls in the mail Saturday and hooked it all up. I was extremely surprised at how simple it is to do the wiring! It made me realize how stupid I was to purchase a tankstick in the first place.
All of the wires worked and I was able to put my PC into the system. I am a bit bummed because I cannot play games like street fighter, marble madness, and golden tee. I have decided NOT to modify the control panel to include a trackball because that would look ridiculous. I am still considering adding two buttons on each players side for a 6 button setup to allow street fighter.
I know, I know. Don't want to modify the MVS too much. I just figure it was completely broken and I am wanting to just keep the iconic look while having something I love.
I also figured out a way to get the marquee lit. The lights that were behind the 4 mini marquees were dead and I could NOT figure out how to replace them (chemical lights or something?) I went ahead and cut the bottom half of the wooden insert out, taped the mvs mini marquee slot to the front window, and bought a $9 light at Meijer. This light gave a soft shine to the marquee which was EXACTLY what I was hoping for :-)
My next plans : Figure out how to mount my LCD monitor within the cabinet, set computer to auto boot on power surge on, sift through ALL the games to remove broken ones and ones that won't work with my setup.
Picture time!
Some coins I found while cleaning dust out of cabinet.







Below is pics after I started taking off the control panel and preparing to gut the machine for mame.


NEW BUTTONS!
