Oh, here is what to do about your mini.
Get yourself to an arcade auction. Hope and pray that there is a lot of grey market gambling stuff. If there is, then you are in luck. Look for a 13" gambler with board problems (garbage on the screen). You can probably get it cheap. Put the monitor (will likely be a late model monitor with some mild burn, but many years of service left), in the Turbo, sell the video poker harness, PCB, power supply, control panel, and monitor plexi, which SHOULD pay for the machine. Then you can use the cabinet with a 14-17" PC monitor to make a cheap Mame cabinet.
