  1. Midway Extra Bases odd board issues - Midway Card cage system (Gorf, WoW, Space Zap, etc)

    I have a Midway Extra Bases that has been running ok. It was definitely overdue for a Power Supply rebuild and a re-cap on the monitor. While waiting on the capacitor kits I decided to pull the card cage to wash those boards and go through them. Plan on adding the clip on heat sinks on the...
  2. TEC TM-623 horizontal and vertical centering?

    Do any of you know how to adjust the horizontal and vertical centering on a TEC TM-623 monitor? I'm working on a pair of Atari Starship 1 games. Notice the picture seems shifted on one of them. Oddly enough it looks like it may have always been that way since the target sticker is also offset.
  3. 19V1001 are P277 and P292 boards interchangeable?

    I've seen 19V1001 black and white monitors that use a P277 and others with a P292 board plugged onto the chassis. Trying to find out if those boards are interchangeable or if there are differences on the main chassis where it makes a difference which board is installed and has to match. If...
  4. Midway A082-90411-C000 power supply schematic wanted. (GORF, Wizard of War, Space Zap, etc)

    Does anyone have the schematic for a Midway A082-90411-C000 power supply? I can find references to a A082-90411-A000 but not the -C000 version. It looks like many -A000 have a few components added afterwards as a mod on the 3532 chip which don't seem to be on the -A000 schematic. It looks...
  5. Berzerk - Reference photo request to help with restoration effort.

    I recently bought an original dedicated Berzerk project game and bringing it back to life. Found three corrupt EPROM chips, burned replacements, cleaned bad connections, removed the battery, and found that two of the interconnect ribbon cables were plugged in off by one pin. Also rebuilt the...
  6. G07 B+ voltage low (around 85V)

    I've searched the forums for G07 low voltage but most seem to talk about not being able to adjust to 120V and the definition of low is a few volts lower than that. In the last couple weeks I've rebuilt 7 other G07 chassis with good results. A couple were a pain but got past all of them. Now I...
  7. SOLD - GAME Playmatic CHANCE pinball machine - Project game - $200

    NLA - SOLD - Selling an early solid state pinball machine titled "CHANCE" by Playmatic out of Spain. I believe these are pretty rare within the US. Missing the backglass and legs but otherwise seems complete. Looks like a folder of paperwork is inside the cabinet along with the coinbox and neck...
  8. Blacklight tube and bulb options for early video games (Midway, Atari, etc)

    I've read that there are variations on the Blacklight tubes used in early arcade games and want to see what my options are and what ones may be best. What are the current best blacklight tubes to look for? Some of the different things to consider: - How bright is the replacement compared to...
  9. FIXED - Missile Command ~ Image upside down in upright cabinet and game automatically starts.

    I have a Missile Command upright that works well and plays without issues. With a known good cabinet and power I’ve been using it to test a couple extra boards. Just fixed one of those Missile Command boards for a friend so he could finally get his game running. Now I am trying to wrap up...
  10. Missile Command PCB - Works with Braze Kit installed. Watchdog kicks in without it. ROM issue?

    I had a couple broken Missile Command boards and a friend asked me to fix his board too so he can finally get his game running again. I was able to get one of my boards totally fixed and running well. I think I have most of my other spare board working now. Just need to test that in my...
  11. Specs on WG 19K7689 monitor?

    What is up with the later Wells Gardner monitor model numbers? Does anyone have a document or site that lists all the monitor model numbers and their specs? Seems to be lacking for the later models. I have a WG 19K7689 that I inherited and since the CRT is perfect would like to revive. But...
  12. Omega Race Power issues - Original Linear Power Supply

    Trying to revive an Omega Race upright and am running into an odd issue on the original power supply. I verified all the correct voltages are present going into the Power board. The power board has had the electrolytic capacitors replaced. Without a load I can get the 12V out and the 5V out...
  13. Help identifying 80’s Williams boards 5780-10211-00 REV X0 and 5770-09959-X2

    Came across an interesting pair of Williams boards that could be prototypes. The part numbers are 5780-10211-00 REV X0 and 5770-09959-X2. Looks like one may use a 68000 chip but that socket is empty. Anyone recognize them?

  15. G07-CB0 monitor dead. Blown F901. Not any of the normal suspects. Why are there so many threads about troublesome G07 monitors?

    I expect that there are a lot of threads just because so many of these monitors were made and they were popular. Before jumping into the issue first a bit of background. Recently picked up a GORF upright machine. Game I've had on the wishlist for a while. The game is clean and seems to be...
  16. GORF - Reviving a project machine - New project

    Recently picked up a GORF project game. Overall it seems to be an intact survivor game but has been sitting for a while and needs some TLC. The person I bought it from tried to do some work on it but didn't get too far. Supposedly the monitor wasn't working and didn't have any neck glow even...
  17. Reviving a Midway Space Encounters

    Trying to revive an old Midway Space Encounters. Game wasn't working at all but is now showing some signs of life. Did some initial adjustments on the monitor and it is working. Temporarily popped in my spare 280 ZZZAP boards to confirm the screen works. It needs cleaning, recap, and...
  18. Safe cleaning of two way mirrors in early games - What is best?? - What to avoid??

    I need to clean the two-way mirror on a 280 ZZZAP as part of the restoration I am doing on that game. Have everything running well but the two-way mirror definitely needs to be cleaned (along with the face of the CRT). Before I do that I wanted to find out if there is anything I should be...
  19. Restoration of Midway 280 ZZZAP

    I've been working on a 280 ZZZAP project for the last few weeks. It has been a lot of fun so far and I learned some new things about the old Black and White monitors along the way. There is a separate thread on my monitor issues. If you want to read up on the monitor issues and how the issues...
  20. WTB - Motorola XM702 chassis (XM501 or XM701 may work for parts) 23" Black and White monitor

    Hello, I'm looking for a spare chassis for an old Motorola 23" Black and White monitor. A chassis from an XM702 would be ideal but I think a chassis from an XM701 or XM501 may provide the parts I need. Anyone have an extra out there to help save an old game?
