TimC Posted January 14 Share Posted January 14 My setup is a newer Dell flat screen that supports 15khz and PAL/NTSC. VGA works great for my Atari STs I have one MegaST with the numbers C10051-001 rev 1.0 and CA200092 on it. I can boot up a game such as Medway Boys 3 (for Ultima 3/4) and I see the garbled video then I can hear the splash screen audio but the video goes blank. So it appears the computer is working just having an issue with video. I also tried it with an RGB2HDMI pickup board and still no video. The Atari ST diag cart produces a blue screen but no text. It then switches to red. Any idea where to start troubleshooting? This one has a C070713-002 shifter. All my other STs have the C025914-38A shifter.
