Paul Westphal Posted July 27, 2014 Share Posted July 27, 2014 The last two xegs I bought have bad ram. I would have thought maybe one out of two would work, but no. Same problem. Did they all ship with the small ' blow up your ram' ingot power supplies? Neither of these came with one so I assume they were the crappy ones and blew the ram. Or Is is that the late ram chips were just crappy? Yes, I will try to replace the ram without pulling up the traces, but sheesh! Can I put two 64k chips in their place?

I don't think XEGS' ever came from the factory with "ingots". I don't think any of the XE's came with them for that matter. I believe they were a product during the XL releases. I'm not 100% sure though. Didn't you mention that you got two XEGS' for really cheap recently (or were getting them). Sometimes you get what you pay for.

Rybags Posted July 27, 2014 Share Posted July 27, 2014 The MT Ram are the usual bad ones. Luckily the XEGS uses 2 x 4bit chips which are pretty common and easy to aquire (plus it's much quicker to replace 2 rather than 8 chips) I've got near 20 of the things laying around, got all of them off old late 80s PC video cards.

Paul Westphal Posted July 27, 2014 Author Share Posted July 27, 2014 Yeah I took a chance, but if all I have to do is replaced ram, then it's still totally worth it. You get what you pay for. I have a friend who is better at soldering and de-soldering than I , but I'm still going to get a solder sucker, and jump in and practice on a cracked board.

BillC Posted July 27, 2014 Share Posted July 27, 2014 The method of replacing the RAM chips with the least risk of damage to the circuit board is to clip off the legs then desolder each individually. Quote Link to comment Share on other sites More sharing options...

Paul Westphal Posted July 30, 2014 Author Share Posted July 30, 2014 I replaced the ram on one and no dice. Still have a green screen. I'm just going to buy some new boards...it will be a good selling point, but I will have to ask more for them. I don't sell junk! Quote Link to comment Share on other sites More sharing options...
MEtalGuy66 Posted July 31, 2014 Share Posted July 31, 2014 how much you want for the old boards? Quote Link to comment Share on other sites More sharing options...
