DavidMil Posted June 18, 2017 Share Posted June 18, 2017 I have an old 5200 that has been in my attic for about 32 years, and I decided to fire it up the other day, All I get is a deep blue screen. My question is about the three large chips (Antic, GTIA, and the Pokey chip), I noticed that the Field Repair Manual lists them all as custom versions of the normal chips. All use the normal part number but all have XX after them. Where they custom versions of the normal chips or is this typical mass confusion from Atari?

CPUWIZ Posted June 18, 2017 Share Posted June 18, 2017 Not sure what you mean. They are all custom chips. Or are you wondering if you can swap in chips from a 800 for instance? If so, the answer is yes. Quote Link to comment Share on other sites More sharing options...
SignGuy81 Posted June 18, 2017 Share Posted June 18, 2017 I would try reseating all of the chips first and see if that brings it back before trying to swap any if you haven't already done so. Quote Link to comment Share on other sites More sharing options...
DavidMil Posted June 18, 2017 Author Share Posted June 18, 2017 Or are you wondering if you can swap in chips from a 800 for instance? If so, the answer is yes. So they weren't special versions of those chips? I know that Atari had a special version of the 6502 chip, I wasn't sure if there were custom versions of those custom chips too. I've already tried reseating all the socketed chips and I've tried swapping out the 8 RAM chips (and the 4050 chip) too. I was going to start swapping out the big chips next but wanted to make sure I didn't need to order something special from Best Elect first. The color does change by turning the veristor.
