Madman Arcade Update (5-16-2009)

Well since I have a few updates, here's yet another posting...

 Atari Video Pinball: ALIVE!! I picked up a donor Motorola Xm501 monitor yesterday on the way back from a business trip(Thanks Rob!). It had the proper 22vatp picture tube I needed.  I tried the Moto first but for some reason it didn't work with the game, so I opted to swap the tube over. Once I swapped the tube I now had a picture, but a very dim picture. In doing some testing I found that the collector of Q203 (D40P3 transistor) wasn't showing 46v like it should. I found one I could temporary swap over (from a 19v2000), and now have a good picture!!

Mounting the tube/chassis back into the mounting frame wasn't fun, but I got it all back together for now, and played a couple games of video pinball. Sweeet!

I still need a D40P3 transistor (Made by Ge) for this, as well as a bezel.

 In other news, I made some progress on converting the arcade over to tokens. I picked up a couple boxes of coin/token mechs from the Allentown Pinball show, and since found out that those ugly tan plastic coin mechs are easily convertable to .984 tokens! Long story short I started converting a whole pile of them, and then installed them into the Megatouch, Qbert, Pole Position, and Asteroids Deluxe so far. So far so good - no jams!

Lastly - there would prob be more progress, however I've since become addicted to TriTowers in a huge way. Philly TriTowers high score owners beware! Already beat the high score on a few local bar Megatouches, and just today came very close to beating the very high score on my own.

Until next time!

Some quick updates....

 1. Asteroids Deluxe #1 has been sold. It went to a good home up in New York, to another Jeff nonetheless! Hope you enjoy it!

 2.  Asteroids Deluxe #2 is now completed and working again. The ARII board needed to be rebuilt, one of the amp chips replaced, and I want to put the original big blue back in since it seems to hum more with the new one. Other than that it looks great and works great!

 3.  Atari Video Pinball - IT LIVES!! As of tonight, I got the board working!! Thanks to the KLOV crowd I was able to troubleshoot the board and ended up replacing the two Playfield RAM chips (2114s). This is the first time I've done a repair like this, and I'm glad to say it has a happy ending!  Still need a 23" B&W Monitor though. If anyone has one local to the Philly (or close by in Delaware or NJ) let me know!

I'd also like to plug http://www.arcadecomponents.com. Ray from that site was a huge help in helping me get the Video Pinball board working. If you're looking for chips to fix an arcade game or classic console/vintage computer, look em up! They also do repairs.
