mikecad Posted February 2, 2016 Share Posted February 2, 2016 Hi there, I recently acquired an Atari 1040STF with TOS 1.0 and when booting I got a red screen and nothing else. I replaced the TOS chips with known working ones from an STFM and now when I fire it up I get a green screen but with static graphical corruption, the disk drive light stays on and the machine is frozen and gets no further, no actual desktop icons etc. I've tested voltages around the board, chips etc and I see a happy 5v. Any ideas? I was thinking RAM but of course these are soldered in and there is a lot of them Thanks, Mike.. Quote Link to comment Share on other sites More sharing options...
