Otherwise I guess my crossassembler xa would crunch it happily. Nevertheless, in the 4040.zip archive I can only find the copy for the main CPU of the drive. AFAIK those drives have two processors, with one of them doing the read/write to the drives. This is the part I think is missing. Also the copyright message is strange (see below) Shouldn't that be DOS 2.6 and 4040 DUAL FLOPPY?
