Found this guy at my local used store. It's from a Tandy, i don't know what model though, but it refuses to work in a normal pc or my 1000EX, it's got the standard 34-pin FDD plug and the 4-pin power connector, i know it responds because i reverse the cable and the light turns on, but when it's properly plugged in, the computer refuses to turn on, that leads me to believe it's a different pin-out anyone know how to wire it up properly?

Reversing the cable and getting the light to turn on is not a good diagnostic technique - you might be frying something. It should be plugged in the correct way, and only the correct way.

Google that drive and see what it was designed for before doing anything else.

I disagree mike
I used to hook floppies up backwards and since one side is all ground
it doesn't fry anything
not a good idea in any event
liik at the [pcb and one pad will be square not round
\that is the #1 side.
when I tried replacing a floppy on a tandy 1000 a std floppy would not work.
in the IBM world all of the 360k floppies were set as B. or isw 0,1,2 as 1 or 9,1 as 1 ( second drive)
most floppies have a jumper to reset the address.
the tandy 1000 had a very short cable with NO TWIST.
so maybe tandy set the drives as A or the first sddress.
hey its been 25 years!

It is not a good idea to reverse the cables on old Mac, IBM, and Tandy drives because they feed power through that cable.

According to this:

it's 720K. Sure you've got the BIOS set for that?
