I was more hoping for a solution to dealing with the variable spindle speed on the 400 and 800k Mac formats. I picked up an old 9600, but its 604 won't boot anymore, and OS 7.6.1 won't boot with the G3 in it. It was the last hardware Apple sold that could read the 400k format, but they stopped including driver support for the 400k format after OS 7.6.1. Rather than hunt for a 604 processor card, I was hoping to find some vintage computing solution that would do more than scratch my Mac floppy itch, IE handle Amiga and my handful of 1581 floppies too.
