This upright is totally functional but obviously not complete. Built a head around the monitor or just pull the parts for another machine. I believe I still have the original monitor head which will fit a 19" monitor.

Details.
Display. WG D9200 monitor installed inside television case. With arcadeVGA card included (2 year old version of the card).
Computer is an Athlon 2800, 1 GB ram. Installed PCB style inside the cabinet. I can't recall if the hard drive is 40 GB or 80 GB.
Controls include a pair of Happ p360 sticks with robotron repro handles and upgraded springs. Buttons are an off-brand, but work just fine. The trackball is a 3" imperial model with the groovy game gear upgraded encoder wheels. It has a groovy game gear encoder with the switch for the external keyboard.
The cocktail.

Gorf cocktail. Set up for 4-way vertical games, dos and arcadeOS. Has a 300 mhz CPU (which is way overkill for 4-way vertical games), and 19" VGA arcade monitor. The joysticks are 4-way Ms. Pac-Reunion sticks. Although the original Gorf 8-way sticks will be provided if I still have them (I am pretty sure that I do). Glass is in pretty good shape and the control panel overlays are excellent. Monitor and PC inside were all brand new when this was put together and only have a few hundred hours of use on them. I think this has an I-Pac, but it may have a keywiz. Not that the differences between them even matter for this sort of application.
These machines are $500 each. Located in St. Louis missouri. Delivery available for extra money.
