Wrong.  It just isn't in the manuals that come with the box.  Would you give
a software jock connector pinouts?  That's *DANGEROUS*!  Toshiba does run a
customer support BBS at 1-714-837-4408, 1200 baud only.  I got the number by
calling the 800 voice number and asking a techie-type question.  There is a
file on the board called 3100-ibm.txt, which docs the cable in question, along
with files that doc all the other connectors.  Sorry you went to so much
trouble before you asked!

Here's the file, I haven't bothered to check your work Rob:

 1100+ or 3100 to IBM Floppy Disk

I just crimped ribbon cable into an edge connector, flared the other end, and
soldered the individual wires to the tabs of a solder-cup style DB25.  Works
great with a shell around the DB25 for strain relief.  Has been in use for
months... (how did you think I got Minix on the Toshiba in the first place!!)
