S100 spares needed - repairs almost done

Hello, all: Scott has made much progress in repairing my N* machine. Well, calling it a N* is a stretch since the only thing N* about it is the motherboard, case and disk controller. Anyway, I'm having diskette issues. I have two theoretically good single-density controllers and disk drives, and Don Maslin made replacement boot disks for me. These disks don't boot, although the controller attempts to access them. It may be that the replacement SD disks were made from a DD controller, but I don't know for sure. So, I have two choices -- obtain SD boot diskettes made with an SD controller or get a N* DD controller (MDS-AD|AD2|AD3). Any other thoughts or recommendations appreciated. Thanks.
