    [Fixed] Defender/Stargate controls go wonky on JROK

    I've always wondered... When you get the board brand new, you have to load your own roms. Is it possible that it's just corrupt memory and need to erase and reload the rom files? @jrok is really a great guy. I had a problem w/ my original board and he took it back and found the fpga wasn't...

    Solved: Black Hole pop bumpers, help find documentation for fix

    Update. I've found it. A 2 line blurb in the pinwiki site. Just didn't see it the first 3 times reading through. "Also, to avoid random, uncommanded pops caused by "noise" on the switch line, you can add an electrolytic capacitor to the solder side of the board. Use a 4.7 mfd 16 volt radial...

    Solved: Black Hole pop bumpers, help find documentation for fix

    Finally getting around to fixing my Black Hole. One of the last things that's been plaguing me is the pop bumpers. I have done the mods for both reliability and LED convenience. While playing, when 1 pop bumper is activated by the ball, another one fires as well. I know there was a fix for...

    NeoLoch Inquisitor binary files?

    A few years ago, I had a thread that asked about the binaries for the NeoLoch Inquisitor (Old Inquisistor Thread). As was mentioned the Pic Mcu's they use have the security bit enabled. Has anyone attempted to get the person/company who made these release the files? Or, has anyone figured out...

    rom burning issue

    This thread is a month old. Did you ever figure this out? It looks to me, the 29c256 should be compatible, although I've never tried one. Where did you get the files you're trying to burn? I checked the ones on ipdb.org and they should be valid. Don't use the MAME roms What settings are you...

    Williams black knight 2000. Flipper issue

    Don't know this game, but looking at the schematics, it looks as though your Blu/Yel wire is the power wire and goes to fuse F5 on the Aux Power Board. F6 should be the other flipper. Start there and check both. Check the connector 5J12 on the Aux board for burning. You might also have a...

    Price Check: Bally Fireball 1972 EM

    Yeah, it's not my machine. A friend referred me to this 85 yr old guy. My area doesn't have anyone that works on pins that I'm aware of. I just try to be the nice guy and at least look at it for him. I really dislike working on EMs. I was hoping, when he told me about it, that it was going...

    Price Check: Bally Fireball 1972 EM

    I'm looking for a price check on a Bally Fireball 1972 EM. Currently it is "broken"-ish. It powers on and there are 3 coils that need replacing. Besides that it seems to need just a lot of cleaning and adjusting. I was able to get most of it to work by adjusting/cleaning some of the relay...

    Transistor Replacement search

    Yeah, I saw Rochester and found out about the minimum order. Damn! You wouldn't need $245 worth of transistors would you?

    Transistor Replacement search

    It's for an RC car for a friend. He ran it through a puddle and *kaput*. He retired and is currently sailing around "the great loop". He would like it fixed to donate to a less fortunate child for the holidays, Toys for Tots. I'm just trying to getting working again. Thanks for the...

    Transistor Replacement search

    I need help finding a suitable replacement for 2 transistors that are obsolete. Hoping the community can help. I've attached 2 images of the transistors and the specs. My research has yielded a couple of options. For the 2SC3279 -> Fairchild KSC5019 or ONSemi 2SB926 For the A1300 -> OnSemi...

    Spy Hunter Side Art Question

    It is my opinion that it varies as well. From my experience, the factory didn't seem to care. My machine has some of the black showing on the Left side, but it's non existent on the right top (original art from manufacturer). Here are some measurements from my machine. I would say just use...

    Does this battery need to come off?

    The board looks good. But, I just want to correct one mistake. Battery acid is a misnomer. The batteries are made of a Base compound. Baking soda is another base. Basically, it just acted as a sanding scrub in this case. If you want to neutralize the battery, you need to use an acid. Most...

    Does this battery need to come off?

    Good eye. Can definitely see it starting near the dip switch resistors.

    Does this battery need to come off?

    +1 to the "Get that damn thing off the board right NOW!" That battery on sys80 boards, if I remember correctly, only saves the high scores. If you can live without saving those, just remove it and forget about it. If you insist on saving your high scores, either a nvram for the 5101 which...
