Could you mail me a copy of your schematic for your setup on your 
disk drive and the interface to your amiga 1000?

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....

Thanks!
