So i have restored a Taito-Top Speed Machine. It began when i bought a workin one and was given a non working one for free! The working one ha a cab that was in a terrible shape. But i was workin until we moved it from a garage to a location, when it suddenly died. Used the pcb from the broken one and the game booted up again, but i had some issues. Used this fall to do a quick restore and a cab swap. The original cab is beeing transformed, with the help of a kit, to a MK 1. There are currently no artwork for the Taito Machine (as far as i know) and the artwork was in terrible shape. So we did the only thing we could do with it. Rebuild it and repaint it. No one wants to pay much for a top speed as far as i know, so to find the parts and build another top speed was out of the question, but i had a mk1 kit. Here links to some pics.
I have a Neo Geo 1 slot that you can plug in Neo Geo Joysticks into (extra ports, not connected throu jamma), i dont know if its for AES Joysticks, anyway. If you bought one of those, you could do the "Ben heck" build and not have a "cramped for space" control Panel. But i guess thats not the setup you are going for?
Throwing away a "Star Trip" Coctail pinball i had in my room as a "tween" when i moved from my parents house. The boards for score and so was toast, but i could have saved the cab and the playfield.
