I recently pulled an Amiga 500 (Rev 6A) out from storage. It seems to work well, except for a strange problem when an external floppy drive is connected. The 500's power LED and the screen (on an 1084S monitor) dims in sync with the external floppy drive access. When the drive isn't being accessed there's no dimming, although the normal drive clicking every few seconds (when the drive is empty) does result in dimming for the duration of the click.
I tried 2 different external floppy drives and they both do it, although one seems to cause slightly greater dimming than the other. The internal floppy drive doesn't cause the same problem.
Any ideas what might be the cause and how to fix it? I suspect it might be power supply (+12V?) related.
