Saw an ad on Craigslist for five free games so I replied ASAP. The guy was clearing out some room in his garage and liked my email because it was short and to the point. Basically all I said is "I have a truck and can pick them up tonight." The five games included 2-Battlezones, 2-Omega Races, and a Space Panic. This Battlezone was complete, but pretty dirty from sitting in storage for years. At one point it suffered some slight water damage but it isn't too bad. The sideart was originally very dirty and had some oil on it. Magic Erasers once again proved to be magic and after 5 or 6 hours of cleaning the art looks great now. The control panel is in decent condition, there is some rust and some of the paint has worn, but overall it's in good shape... especially considering the price! Over the past few months I fixed the PCB and the game was working... but the HV diode died recently and after replacing it I'm having problems with the retrace lines not being blanked. It's a problem in the monitor because the game PCBs test good in our cabaret. Luckily the person giving away the games also had a couple extra monitors... Hopefully I'll get the game working soon because I'm addicted! UPDATE: 01-21-2010 Created this page. UPDATE: 01-25-2010 Ended up NOT being the monitor... gotta love it. Not sure how I screwed up there... my only guess is the monitor just needed the brightness adjusted in the test rig. Dummy!!! But at least now I have two working monitors and one that just needs a HV Diode. So... I started working on the real problem tonight... the PCB. The Z-output is doing some funny things. Sometimes when you turn the game on it's around .5v while other times it's around 1.5v... it's pretty random. I started tracing back from the edge connector and it seems like the F8 74LS175 is acting flaky. The inputs seem to be correct but the outputs are getting stuck high one time and low the next. There is a 74LS399 at H8 that could be back feeding I guess so I'm going to replace that also. I just need to get both chips tomorrow at the local electronics store. UPDATE: 02-14-2010 The local parts place didn't have a 74LS399 so I went to the KLOV forums and asked if anyone had one I could buy. Craig(aka bit_slicer) replied and sent me a couple for free! After replacing the 74LS399@H8, Zout is now acting correctly. Boy I missed this game. Thanks again Craig!!! I also found the POKEY had 4 or 5 cracked legs during testing after replacing that 399... I cleaned the legs a while ago since they were so dirty and never noticed the "loose legs". After swapping in a good POKEY the BZ has been perking away for hours.
