Here is a picture of the game...I hope

I have a Skeet Shoot game made by Games Inc. and I am trying find some info on it. I believe it is from the mid to late 50s. I can't seem to find it on KLOV and if nothing else I would like to send in some pictures and info to them on the game. I was not able to find the "contribute" button on...

Thank you both very much for the help. I replaced it with a 10mf 50v electrolytic cap I had in the workshop and the game is back up. I wish everything was that easy :) Thanks again

I think I fried a cap on my Wizard of Wor board on start up and wanted to see what people thought I should replace it with. In the manual it calls for a 15mf 50v cap so do I replace it with a 22mf or a 10mf ? They are strange looking caps as they look almost like resistors. When I turned the...

Thanks I will go get some contact cleaner and try that.

Well I just put new caps and an amp in the little board and now the game sounds like it should. The only trouble is if you try to turn it up with the POT it will go into very loud static noise. If I move the POT back and forth I can get it to a usable level. The POT is a RV16YP. Is there a...

I just put my order in for a new amp and caps for the board and will post back when I have them installed. Is there a site that would have the schematic for this little board? Thanks again, Scott

I do get the sounds from "L" but not the cream colored wire at "M", so I guess the little amp board has some problems. I do not have a link to the schematics for this board. If you have it that would be great. While working on the game the monitor on the game went dead again and blew fuse 901...

I have a Mr Do's Castle that I have been working on and now need some help with the sound. The game plays fine except for the fact it has no sound. I am assuming that the little board by the coin door is a amp of some kind. I have four wires going to this amp board...a black GND wire coming...

Thanks for the answers.

I love to come in here and just read threads. I keep seeing the term DAC when people are talking about parts on a PCB and for the life of me I can not figure out what part this stands for. Thanks, Scott

My Brother has a GT 2K that he moved from one side of his basement to the other and now the trackball will not work at all. He said he has checked the connections and he has 5vdc at the trackball so what else could it be. He has also tried switching boards in the trackball with no luck...

I removed the sockets from E2 and the CPU and put in new SIP sockets with no change. I am going to remove and replace the other three sockets and see if that helps. I was also going to repin the connector as the game started drawing strange lines then showed what looked like the test pattern...

I removed four 2114 chips off of a Galaxians board and piggy-backed them on chips M4,R4,N4 and P4 with no change in the way the game acted. E2 according to the test was the 2114 that was bad but it is not a 2114. It looks to be a ROM/PROM chip. Is it better to go with a High Score save kit...

I do have all of my voltages and they are correct. I am getting 5.2vdc on the A/R board and dead on 5vdc on the game boards test points. I had re-seated the chips before I posted but will give it another try tonight. Both the edge connector and PCB fingers look nice and shiny. I will order...
