Looking for used or project. Thanks.

Frogger Is Frogger still available? Price? Would you happen to have a lead on a Dig Dug?

When I move the target around the screen it leaves a trail of red dashes behind it. Can anyone suggest a possible fix for this? Has anyone else had this problem? Thanks.

update i tied the red circuit to the green gun and graphics are fine. i tied the green circuit to the red gun and red gun is working. but when i have the red circuit and red gun connected like normal, the red is very weak. this doesn't seem to make any sense. something I'm missing?

Wherever the target moves around the screen it leaves behind permanent trails of red dashes. Has anyone encountered this issue or have any advice on where I might start troubleshooting? I looked through the user manual, but could not find anything. Thanks in advance, Roger

Ok, I give up. Does anyone do in home crt repair in the TX D/FW area?

When I turn red all the way up, the graphics and entire background are a very faint red. Could this be the gun failing or would it be something elsewhere (like a transistor, etc)? There is one thing I noticed and I would like to know if it could be part of the problem. On the game pcb, where...

I just want to confirm that you did mean to say INput transistor and not the OUTput transistor. Thanks!

How do I short the red gun to ground? To turn the red gun all the way up, do I use the drive pot or the cutoff pot? BTW, cutoff and output are the same, correct? Sorry, I'm still learning.

If I understand correctly, the three color output circuits are identical, so I figured I could just compare the voltage measurements before removing the transistors.

I searched past posts and gathered all the info I could. While I try troubleshooting with some of that info, could someone answer the following question? What should the voltage measure at the collector, base and emitter of Q401 (red output transistor)? Thanks so much in advance! Roger

anybody have one for sale?

Hi. My Joust has no sound except it makes a repeating "laser gun" type of sound when the test button on the sound board is pressed. All of the wiring and voltages are correct. I have a few specific questions if anyone can help. Thank you in advance. 1. Should pin 40 of IC9 (6808) on the sound...

Hello. I've had an account here for a few years, but just registered. I've gotten a lot of great information here that has helped me repair my games. Great place for buying and selling as well. I currently have a small collection of my favorite games from when I was a kid. Asteroids, Q*bert...

WTB: Joust sound board Hello. Is the Joust sound board still available? If so, how much would shipping be to Plano, TX 75023? Thank you. Roger
