CPS never produced their own hardware but they did bundle their software with the Vtech UDC card and sold that. It would only handle 3.5” disks up to 800k though.

A while back Reactive Micro produced a Superdrive card but I believe it used the drive controller chip from older Macs so production was limited to a few cards and it’d no longer being made.

There were the Blue Disk and Urpi controllers but they used PC floppy drives
