So, trying to figure out this problem with Joust and I'm determined to get this going again as it's slated for restoration. Here is the story on it.
Was playing one night last summer with a friend. We got to level ten and the game just froze. I turned it off and then about ten seconds later I turned it back on to find it still frozen instantly at level 10- strange. I again powered it down, and came across scrambled junk.
After figuring nothing out, ( I gave up easily) I sold it to someone in a package deal, had seller regret and was able to get it back tonight. (thank you to them, because I love this ridiculous game)
The boards look good, there is no corrosion or anything like that. The 3 leds are on, on the power supply. I tested the test point 5 at 14 volts and change, and the one near the top under the connector (forget the TP number) reads nothing. The large capacitor on the power supply has a slice like crack on one end (looks to be the original cap) Other caps look newer.
Solder has been re-fllowed on the connectors and the connectors are not burned here or anywhere, they look to all be in really good shape. All fuses check out good out of circuit. At power up, it just faintly flickers the 7 segment for a split second on the rom board. The screen shows a bar patern, and that's it.
Anyone have any thoughts? The only other thing is there is a thin blue jumper hanging off a prom, that is on the rom board, and I'm not sure what this is but it's from a previous owner. Not sure how crucial this ''wire' is or isn't.
I also tested the volts at the chips on the rom board and I'm getting 4.96- Doesn't this need to be over 5 to boot up?
Any help is greatly appreciated,
thanks, James
