Hi All:
I recently bought a "toasterscan" scan doubler/flickerfixer from Software Hut for about $145. Just plug on to the video out, plug the VGA cable into the other end, and it works. I have a A4000, but there is no obvious reason it shouldn't work with any amiga. I could drag out my old A500 and try it if you are really in need of assurance and really interested in this fix. I must add that it doesn't deal well with PAL screen (they get all fish-eye looking). Best flicker solution I ever found was an old C2080 slow phosphor monitor (identical to a 1084 inside). It was great, but it seems to have burned out.
