I have a tandom drive 40 track also, and I have been having a heck of a time getting the amiga side to recognize it. the ibm side works most of the time, but I think the problem is a timing difference for me... I only have an amiga 1000 right now.... Hans Bechtel 12627 Singing Arrow SE Albuquerque, NM 87123 (505) 293-7585 (or email me the schematic if it is possible...) Thanks!
