I just picked up a Madden Football cabinet made by Global VR. The game runs on a PC which was not included with the cab, but everything else was. I made a web page with some pictures since I didn't find much of anything about it on the web. One of the cabinet parts I thought would be of interest to this group are the 2 Nytric Extreme USB control interface boards.
The control panel has four 49 way sticks with four buttons per player and four start buttons. The wiring for the controls is separated into P1/P2 and P3/P4, and the harnesses are identical. It's a nice design as it makes a 2 or 4 player cabinet easy to build by just adding another harness.
The controls all go into a PCB labeled Nytric Extreme. A web search turns up the company that made them, but I didn't find a pinout. The cards look PCI based although the edge connector is on the back side rather than the bottom. The card is powered by a standard PC power plug hooked to a switcher in the cab. The card outputs via a standard USB cable to the PC. I found mention of drivers, but didn't find the actual files.
I think I'll be tossing these up on eBay, but wanted to document it as I thought it was a pretty cool setup.
