Several months ago I purchased a Toshiba 1000 laptop. I am interested in finding the specifications for the external 5.25" drive expansion port. I need the pinouts and any documents that show actual useage of the port. Any mail address you could give where you KNOW I can get this info (and what to ask for), or E-mail would be appreciated.

Tom, I posted an entire procedure on building an external drive for the T1000 a few months ago, but my archived copy of it is on a disk five miles away at the moment. The only thing I can lay hands on at the moment is the list of pin connections (below). If this isn't enough for you, send me e-mail as a reminder, and I'll go through my mail archives. Several people have succesfully built external drives from my procedure (including myself, of course) -- it cost me about $100, but I didn't hunt for bargain components, just bought a traded-in 5-1/4 drive from a local computer store, and a Tandy Color Computer disk drive enclosure and power supply surplus. The pinout listing that follows was orginally downloaded from the Toshiba Laptop BBS at (714) 837-4408 (2400 N81). I developed the procedure from this. I've posted the complete procedure to this newsgroup at least twice, so it may be archived somewhere (I have no idea where, though). Maybe I should write a script to post it once a month for new readers of this group... . ;^) Hope this helps you. -coryc Toshiba Laptop to standard IBM type floppy drive.
