I've got one of those here (I'm at McGill in Montreal, Canada) I
couldn't find a use for it (I hoped to take the drive out to put into
a 1581 kit I got earlier this year) so it's free for shipping to
anyone who wants it.  (please contact me off-list)

If noone takes up my offer, I would like to attempt to do something
useful with it - maybe build a simple 4865 to A1010 (external Amiga
floppy) converter?  Should only require a flip-flop - and it'd be
useful to me since an A500 ended up donating its drive for my 1581 :-)

If you could send me the pinouts, it'd be appreciated!!

Joe.
