Silly question, I know, but why not just use a 1.44MB 3.5" drive?

You're correct that it doesn't support the 1.44MB format, but so long as you use DS2D (no density aperture) media, a 1.44MB drive will support 720K just fine.
Take a look at the attached image. The floppy on the left is DSHD; the one on the right is DS2D. If you cover the density aperture over with a bit of opaque tape, you can make a DSHD work in a pinch.

That's it. No need to go looking for a 720K drive.

Ebay's full of them. Right now, there's a bunch of 3 with a bid of $0.99 and free shipping. Nobody wants the things nowadays. If you've got a local recycler, they'll probably give one to you to keep it out of the landfill.

You can use your current controller. However, you'll need a power cable adapter for the drive, as well as some way to connect your floppy cable to the drive. You can sometimes find 34-pin edge connector-to-header adapters or you can make your own cable.

Ahhhh, so apparently any old floppy drive is fine. I was hoping to find one in a 5.25" form factor so it would mount nicely in the IBM case. I have plenty of these drives around. Where would be the best place to look for an edge connector-to-header adapter?
