I Guess Arcade Games Will Survive an Unheated Garage My mom put my Stargate Defender, Defender, and Multi - WIlliam in our garage in Chicago. So for maybe 2 year they went through Chicago winters and summers, no climate control in the garage. I fired up all 3 and only the Multi - WIlliam...

Ok, it was a loose connection on the Stargate and the Defender was missing a main circuit board.

Ok, I will check for loose connections.

I haven't been on this forum for a long time because maybe 2 years ago I went onto a morning job interview, and my mom used that occasion to stick my 3 arcade machine into the garage. Our big strong neighbor Ritchie did it all by himself. I hated what my mom did and I feared the hot & cold...

How much do you earn monthly keeping your Tron on the floor? Chicago arcades have disappeared. Nowhere to go to play arcade classics; you gotta own them instead!

You can also buy expensive Lithium AA's from Menards. I got nothing against you, Riptor, I just feel the Lithium Mod is not worth it for Defender based on other people's experiences.

I regret buying 4 Lithium Battery Mods from Riptor for my Defender boards. So I went back to this on ebay - http://cgi.ebay.com/Williams-3-AA-Solder-Type-Battery-holder-Pinball-Video_W0QQitemZ270529186561QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item3efccbcb01#ht_1050wt_1173 Lithium Battery...

It seems Williams made 2 errors then on their Later Series Drawing Set...

I'm stocking up on replacement chips for my Defender boards, but there is a problem. The Later Series Defender drawing set calls chips 1C & 2C as either a 74LS89 or 74LS189 or 74LS289 chip. But I look at my 3 Defender boards and the 1C & 2C chips are marked SN7489N on them, so they're a 7489...

TRON can be rented on Netflix ; I just saw it recently.

See post #12 from Yellowdog.

OK, silly me guys. I pulled the board out and then discovered it was missing chip 2E, a 74LS257 Quad Data Multiplexer. Will order it from here! http://unicornelectronics.com/IC/74LS.html Now things don't look so bad now that I know it didn't work from 1 missing chip! Problem is now I gotta...

Hey Yellowdog - my 4 Stargate Sound Cards can all be fixed but they are a lot of work! I already have 2 great working sound cards so I don't need 4 more. That's why I tried to sell 3 of them on ebay. I should have just waited to buy a working Defender Board set from you but you were taking so...

Yeah, totally DEAD discouraging! No video screen, sync, or message. Could be a lot of problems. It would be a Proud accomplishment if I can fix this board! Now I got good equipment at my disposal! Just gotta finish lengthening my logic analyzer probes and I'll start testing. And I got a...

I have to rely on MAME for anymore video game I want because my house has no more space for more video games. So I have to settle for MAME controllers. I'm in the process of building 2 MAME controllers so I can play Tempest, Stargate, and Tron. My Logitech Gamepad didn't work well for Front...

IS USPS Shipping Insurance Worth It? The only problem comes when USPS loses your package, and how often does that happen? Have you guys ever shipped a lot of packages on USPS and lost one? I plan to sell lotsa stuff on ebay so I need to know!

Even if I bought that BP Micro Eprom programmer I would not know how to duplicate my Stargate & Defender ROMS. And then I wouldn't know where to buy the Stargate & Defender EPROMS for cheap. I'll just let Steph the expert at Hobbyroms do the ROMS for me... ALL I need is a cheap & good enough...

I never knew a coin op Red Baron existed; never saw one bitd. I sure would have liked to try it out! But nowadays I play the PC video game - Rise of Flight, from Fry's. It's not sold at Best Buy, maybe try ebay too...

Thanks for the tips, Yellowdog. I'll try changing out all the RAM and the CPU first too see if that fixes it. When I shorted out my RAM on my Stargate Rev B board it gave a totally dead video screen too. It's so totally discouraging to get an untested ebay board and they turn out all dead...

Thanks for this info, Yellowdog... I guess I'd only use this device as a Logic IC Tester. I know nothing about reading or duplicating ROMS... Maybe I'll just rely on Hobbyroms.com Maybe he uses a good expensive EEPROM burner for his stuff...
