I have been having problems with my super mario. I checked the voltage against what Ken put up. My 5v are coming up 5.1, 12v are coming up about 11v and the 24v is 21v. If I were to replace the capacitors in the power supply will that most likely correct the voltages?

I owned an Upscope and tried to restore it. They use an old style Commodore board. Bought one on line but still couldn't get it to ever play right. One time I got it up an running, then shut it off and couldn't get it up again. Not much info on the game out there. Finally sold it.

I found this thread and it is similar to my issue. Game will come up, but is frozen when 1-1 screen comes up. I sent board to Eldorado and they said it checked out. Any ideas? If it is power supply what volts should I look for?

My Mario brothers is not working. I get an error screen when I turn the machine on. When you push player button the game play screen comes up, but is locked and you can't move Mario. I've attached a couple of pictures. Any ideas would be appreciated.

The numbers on the chip are SYVANTEK-9050 SY06116L-70TP I don't think it is a ROM Does it sound like a bad chip?

I put a new board in my video slot. It worked fine for a short while and then the screen turned to 100s of small, colored squares. One of the chips is quite hot. Is this a bad chip. If so where would I get one. It is a LUCKY 8 LINES 8 LINER PCB.

Does anyone have details about a large collection of pinballs in Cando North Dakota. I'm heading that way and would love to see it. I saw an old post from 2005 on a different forum that talked about it.

The graphics make it look like a video slot machine. It cherries, bells, etc. I've attached a photo showing the harness for the board. Two separate plug ins. Let me know what you think and if I could find a board for this game or something that would fit.

I've attached a picture of the game. Can anyone identify?

I purchased this game at an auction. Turns out someone took cpu part so all I have is monitor and cabinet. Does anyone have advice on who made game, where I could find the cpu, or where I could find replacement game. It looks like it is a video slot machine from the graphics. Thanks for any...

My High Speed has been working fine, but now a problem has started. When I turn it on the pop bumpers and the jet bumpers at the bottom of the play field don't work. After awhile they begin working, its like they have to warm up. I've checked all the fuses and they are good. Anybody have an...

After reading the numual again I see where it talks about a slide switch. I'll have to look for this when I get time. Thanks again for the help.

I checked the test switch and it only has continuity when pressed. Can't find another switch for play. I have a copy of the manual has well, but it doesn't say much. I will trace the wire back and check the connections on the board. I had the game working once and then shut it off and now...

dumb question, what is the BAME board? I assume it is the daughter board attached to mother board. I bought an aftermarket power supply, but have verified the voltages coming out of it to the Amiga Board. I'll check the connectors as you suggested. I'll also work on the capacitors. I've...

I bought one a couple of years ago for $600. It needed cleaned up, had moderate wear, but works great. I replaced rubbers and a few minors things. $1600 seems like a lot unless it was in perfect condition.
