A friend of mine came across a TZ sample game in the wild. He called me up and we started comparing notes on this TZ and the differences. Unfortunately no red boards and missing spiral plastic from the left topside, but all else seems to match up with other documentation I've found on Pinside. There is one thing I haven't seen before and neither has he after working on many TZs in the past. In the upper right hand corner mounted on the ramp is a plastic cover covering the switch. Does anyone else have this? It looks factory installed to us. I believe I read somewhere that the sample cabinets also were missing the stars at the top on the backbox (attached is a pic of the found cabinet and a pic of my friend's backbox). Also the expansion board in the backbox is installed in the lower left on the side of the cabinet instead of the upper right as my other one is.
She's pretty filthy, but will be purty when we get her done. Ordering a few parts, but not bad overall. Real happy to get this early game with the third magnet. Someone put the L3 ROMs in it. Is the prototype ROM needed for the third magnet to activate?
