IBM 51TD

[RetroAND]

Hello,
I am a collector of old computers and I own two IBM System/23 Datamaster computers.
The case that brings me there is that the floppy drives aren't working that fine, also, one of my machines is only comprised by boards, so it has no floppy drives.
Please, I would like to ask what would be required to make a gotek with flashfloppy work replacing an 8 inch drive using the IBM protocol and settings.
Thank you very much for your time and patience.
