What sort of computer did this drive come from?

I've just started on my first wearable, starting from a cut-down
and repackaged Thinkpad 360.
Guess what... It's floppy drive is a Teac FD-05HG.

The floppy drive in my Toshiba T1000SE (we've heard that sound before :)
also has a 26 pin flexible cable connector, but on a larger pitch.

I really don't have any idea what the pinouts are, and I don't really
have a reason at this point to check it out properly,
but I have a theory. :)

I _suspect_ the pinout to be similar to the standard desktop drives,
but with the pins not pertaining to just a single drive removed.
i.e. The reserved pins, Drive select 1, and the Motor enable pins (aka
Drive select 2 and 3) and their associated grounds. 
That leaves us with 26 pins.
We still need to get power to the drive, and we don't nescessarily need
the index pin (do we? I know the drive doesn't have a sensor, but it might
be simulated) but I think the power is split among th usual ground wires.

Curiosity demands further investigation.
I'll get back to you if I get around to checking things :)
