130XE troubleshooting in Atari 8-Bit Computers Posted November 29 4 hours ago, hueyjones70 said: I have had computers that didn't work because of bad ram but I've never had one that worked intermittently due to bad RAM. I'll probably go ahead and replace it because it is MT RAM and I will just cut out the RAM chips so there is little chance of lifting a trace. With issues likes these, sometimes the only way is via process of elimination. I have an idea. Maybe you can post a picture of the top and bottom of the motherboard. There are a lot of sharp eyed people here. Maybe they can take a look and see if there any physically amiss that can be causing the issue (i.e. bad caps solder joints).
