Ianr757 Posted February 9, 2020 Share Posted February 9, 2020 Hi all, I just recently picked up a copy of Pitfall 2 that has seen better days. After extensive cleaning with alcohol, the game still doesn't work. Based on the pictures, does it look like there's any hope? Thanks!

ColecoJoe Posted February 9, 2020 Share Posted February 9, 2020 Hard to say. Some of those traces look like they are missing some copper. Try this stuff before you give up. https://amzn.to/2SyF1Wg Quote Link to comment Share on other sites More sharing options...
+jsmith73 Posted February 9, 2020 Share Posted February 9, 2020 (edited) Might be salvageable. Depends on how far down the rabbit hole you want to go. With just the pictures to go by there's every chance that the copper has corroded away underneath the conformal coating. The bubbles you are seeing are a dead giveaway of corrosion damage. If you are feeling brave, you can gently scrape away that coating to get a good look at the traces. You might be able to get away with flowing solder along then to jump any missing spots if they're not too large. You might also desolder, remove and then re solder the DIP. Give the deoxit a try first. Edited February 9, 2020 by jsmith73 Additional step 1 Quote Link to comment Share on other sites More sharing options...
Ianr757 Posted February 9, 2020 Author Share Posted February 9, 2020 Thanks all, I just ordered some of the deoxit and will get back to you when I try it out. Still open to other opinions as well, thanks! Quote Link to comment Share on other sites More sharing options...
Ikrananka Posted February 9, 2020 Share Posted February 9, 2020 You could also test continuity of the traces using say a multimeter. That way you'll at least know if any traces are damaged. Also, reflowing the solder at the pins of the ROM might be necessary, but in itself could cause more damage from the heat on the corroded surface of the board.

Ianr757 Posted February 12, 2020 Author Share Posted February 12, 2020 Update: the deoxit didn't help out unfortunately, so I'll turn to some of the alternate suggestions you guys have mentioned. Thanks for the help! Quote Link to comment Share on other sites More sharing options...
MrPix Posted February 12, 2020 Share Posted February 12, 2020 I’m making a new batch of those PCBs in about a month. If you’re still stuck drop me a PM and I’ll mail you one. Quote Link to comment Share on other sites More sharing options...

I'll admit ignorance here, but would that mean that I would just pull off the DIP and solder it onto the new PCB? Quote Link to comment Share on other sites More sharing options...

That way, if the ROM is bad too I could burn you an EPROM. Quote Link to comment Share on other sites More sharing options...
