Greetings fellow techies. Have a Tron with the hobbyrom HS save and freeplay. Worked fine for years. Recently moved the game to a new location. Upon power up the game works fine but the HS/Free play is disabled somehow. No saving games and have to coin up. Does that make any sense? Any...

Hi Techs - could use a little help diagnosing a developing issue in my Tron cabinet. Setup: Running off Switching PS and MCR adapter board. Testing steady 5.38v on the lugs of the PS. Testing 4.98v on the cpu chips. I have cleaned the connectors and de-oxed the pins on the cpu. Problem...

Hi All - Recently finished a Galaga build for a friend. In order to keep costs in his budget I did a vinyl print bezel. He decided after to change it up and go more custom so I have the version I printed on glass. Obviously never can match screen print quality but I do have a very high end...

Hi guys, Looking for a little direction on some color problems on one side of my nintendo VS. board. Running SMB and golf on this particular board. (I also have RBI/Castlevania on another board and both boards are connected to the vector labs switcher) 3 of the four games look and play great...

Hey Tech Gurus, Had this Gyruss for almost 2 years playing great. Last couple times I played the ships turn into these blocks intermittently. The scores and text look good but the ships are squares. Tried the basic edge connector and harness cleaning but its still happening. Voltage looks...

Greetings All, Have an Asteroids project game in process. The quick and dirty is that is was one of the more water logged machines I've seen out here in the desert. Nice lady stored it out on her patio (must have been through a few monsoons out here). Anyhow, I decided that the world probably...

Hey All, I know there are already plenty of great threads on Pacman Restorations but I thought I'd share my work in progress with a slightly different twist on the cab art. I wasn't too excited about the process of stenciling my cab. After looking at the other threads it seemed really labor...

Hey guys, Trying to get a look at running a championship sprint on a 27" k7502 monitor i found... thinking I may do a custom project cab to house the bigger monitor if it looks cool. Anyway, game runs on the traditional combo of the Atari Power Brick and the 5v switching PS. Looking the...

Hey Guys, Have about 20+ hours into getting my Turbo up and running. Haven't been able to get there yet. Hoping maybe one of you experienced Turbo guys can get me on track. So heres the summary... Had the cab for a year. Played pretty reliably except for the accelerator didn't function...

Hi guys, looking for someone who would be interested in repair on Championship Sprint board set. I have two sets... one that boots to garbage and another that was working well until a few days ago and zap. Seems to have taken out my ARIII too... or vice versa. No 5v to the video board. I put a...

Hoping someone out there with a working Turbo would do me a big favor and post some pics of the accelerator board wiring. My accelerator is stuck on full throttle all the time. I pulled the opt boards and compared to the schematic, the wiring on the two small opto boards looks incorrect. If...

Greetings gurus, Have two questions on the hookups for a k7191 I could use help with. I read on some threads from Ken and Buffet that some cabs can be wired backwards so I'm being a little cautious here. Just picked up an cab that appears to be a Dynamo that has the k7191. The monitor...

Nice Asteroids Upright - $650 Gameroom is bursting at the seams. Had to make a tough call to part with this Asteroids. It was my first cab, but Ive since located a nice AD and don't need both. Had it it perfect working order since I got it 5 years ago. Highlights: Marquee looks almost new I...

Hi tech gurus. Hoping one of you might weigh in on this and that its a simple question. Was cleaning up and recapping my 4600 this morning. I got the width coil a little saturated with iso alcohol. In the process of putting the chassis back together the cardboard type material that holds the...

Hey All Have a recently acquired Craigslist Joust that was supposed to be "working" when I got it home. Have read what feels like hundreds of threads to put my time in. Looking out to the gurus on the Williams games. Hoping you'd be kind enough to take a look at this recap and see if you think...

Hi Guys, Picked up a Joust which had a hacked switching PS. Going to rebuild the original PS with a kit from Bob and see if I can get her to run on original equipment. However, before I start, the original PS has this jumper from what I believe is the ground leg of R21... the other end of the...

Hi guys, The black ground strap on the crt was cut by someone before me... would you tell me the best location to attach? Feel like I've seen these soldered to neck boards among other places. Would like to know optimum location. THanks!!

Hi Guys, I have a 27" picture tube I pulled from a 1997 Sharp. No know manufacturer info on the tube however. Hoping to find an appropriate chassis that will work with the tube. As you can see its a 10 pin fat neck. The resistance measurements for this particular yoke are written on the...

Hi Guys, Have a centipede with a GO7 that likes to go in and out of focus during play. Will be nice for a couple boards and then start to get fuzzy... Then snap back into focus again. Did a cap kit last week. Problem still the same. Doesn't matter how long its been on. Does this sound like a...
