It's a long shot but I twice solved "illogical" (surprisingly also with A2000) issues by finding and replacing (with FB) partially faulty EMI filters. I don't have A2K schematics at hand now (does this revision have Gary?) but since it looks somehow related to floppy circuits (Gotek vs. regular floppy) and possibly a sort of edge-case timing issue - I'd possibly check also around Gary and floppy lines, which can have some EMI filters around the external connector. -- SD! - http://e4aws.silverdr.com/Received on 2018-10-07 21:00:06
