gladders Posted July 19, 2019 Share Posted July 19, 2019 Hey all, I've found a TRS-80 that I may be able to make my own. It looks in great condition although the image is garbled on the screen. Looks like a video RAM issue, right? If so, what video RAM chips do I need to repair it? And where can I get them? Thanks! Quote Link to comment Share on other sites More sharing options...

You need to be more specific. I,III,4,4P,4D,II,12,16,6000,100,102,200,mc-10,coco1,coco2,coco3,2000...get the idea? Also what kind of video issue? Text messed up, graphics, random characters? Does it respond to keyboard commands? 1 Quote Link to comment Share on other sites More sharing options...
