Using 8-inch diskette drives with a PC

I have once stumbled upon an interesting article from 2018 published on, discussing about provisions on connecting an 8″ floppy disk drive to a PC. You know, those huge “boat anchors” that accept flexible disks just four inches shy of an LP record, in exchange of a couple of hundred kilobytes data storage. That sort of type. The experiment there was to connect that big ol’ mainframe-era drive to a normal PC, as to be used under DOS as an archival tool. In 2019, the author got mixed results from his experiments: he was able to fool the system BIOS, tricking the 8″ drive to work with a geometry that of a 5 1/4″ 1,2MB DS HD drive. For the rest, he’d use a proprietary controller card paired with some paid software.

As a follow-up to his article, I’ve decided to tinker around on how to have fun with these clunkin’ beasts using a classic PC equipped with a vanilla floppy-disk controller (FDC); without any commercial hardware, software, or some USB controlled thing-a-magic with Windows 10 support. Besides, 8 inch drives predate PCs as we know them, and classic floppy drives with PCs were mostly used during the DOS/Win9x decades. Behold!

Completely absurd and pointless. Just the way I like it.
