	It might work!  Does anyone have access to one of these and the tape
controller for the 3B1?  I would be willing to try if someone can lend a
drive.  (Or perhaps the pin-out for the drive first, just to check for
design stupidity like putting raw +12V on a pin that the controller thinks
is a ttl input or output.)  I seem to remember one or two pins on the ground
side of the connector being used for something in the floppy tape drive we
have.  The 40MB version may simply use more tracks, or slower tape
speed/denser recording, or perhaps rll :-) ? ?

	If someone does have access to both ends of the question, please try
and post results.

	Good Luck
