Gotek as an external floppy drive

Post by PeteW » Fri Aug 28, 2020 7:04 pm

Currently my gotek is replacing the internal floppy drive on my stfm because my machine had the original drive missing when I bought it.

I recently acquired an original floppy drive so want to put that back in the machine and make the gotek external.

Questions I have:
1. Can I make the gotek into an external drive without purchasing and butchering an old external floppy drive?
2. Can I get the st to boot from the new external gotek if I want to load software from it on boot?

All help appreciated!

Yes, I put a gotek into a 314 case which is used on a MSTE. The gotek was a ST drive A before I moved it no changes. I also had a 354 drive but the floppy connector was some weird thing so you couldn't use it unless you re-wired the floppy connector. I've read some 354's are normal and some have the weird connector.

If you want to reboot off the gotek you need to electrically swap the drives so the external gotek becomes the A: drive and the internet drive becomes B: . I believe some people here have done it so search around for swapping floppy's. Also the H4 has jumpers for that desire I believe.

The "weird connector" is a Chinon one, see one of my earlier posts about changing the cable to be Shugart compatible.

I dropped a Gotek into a Datel external drive enclosure and had noproblems.

That particular enclosure has no internal electronics other than a power regulator and the 14 pin DIN plug goes straight to a 34 pin floppy connector. Which reminds me I need to finish off my wiring diagram and post it on here!

I'd be really interested in seeing that circuit. Will maybe make an external drive style case for the gotek, but if I can avoid using old original equipment, that would be a better solution in my mind

I did make a start on the circuit, there are only 14 pins out of 34 connected, so it's nothing difficult, at least I have one of the 14 pin DIN plugs, which are in short supply it seems.
