KOOBOOK 1Pcs 1.44MB 3.5" Floppy Drive Connector 34 PIN 34P to USB Cable Adapter PCB Board with Power Cable

Works better than I expected. The biggest issues to get tripped on are the power connector(s) and the UBS solder joint(s). Two floppy connector must be used. One to the KOOBOOK and a second one to the floppy device. As pointed out by others the USB connection on the KOOBOOK board is weak. Get your soldering iron and glue gun out, and track down a tie wrap. As you can see in the picture the this device must be treated as "hobbyist" project. For another 10 bucks I would have paid for a case to protect the KOOBOOK and to provide more secure connections.

I thought it would fit on a floppy drive

Installed this on my sleeper build, runs a little on the slow side but considering I'm using a floppy drive on a computer thats nearly 20 years older than the drive itself that is to be expected. The chip itself is a little on the flimsy side, but if you aren't stupid that shouldn't be an issue considering it will live in a steel box. One thing to note is the unit doesn't quite meet the voltage requirement to power on a drive, but its close enough to where it works. Like, the floppy drive will read and write, but its slower than if it were in a machine from the floppy disk era. That being said I'm mostly using this for very basic stuff so speed isn't an issue. 8.75/10, 5 stars overall.

Works as advertised. I can now hook an internal 3.5 inch floppy drive to my main computer. Mostly use it for transferring programs to and from my old Windows 3.1 486DX2 66.

I got this to get my tower PC an internal Floppy drive. While it does work and fits nicely inside my PC without protuding for some reason it's limit to only reading 1.44M Floppies and 720K Floppy's don't read. Not sure if this is a limitation of the adapter or the drive itself, but for what I needed it does work
