The list is quite incomplete. For example, Ultrastor ISA SCSI cards
used it (I have a 14N, for example that even supports 3 drives on the
same cable). Many DTC controllers can do likewise, though the FDC
often bears a DTC part number.
There are also some MFM and RLL and ESDI controllers that use the
same chip, but I'd have to go back and check my notes. I have a DTC
ESDI controller here that will support 4 floppy drives on a single
"flat" cable, for example.
DTK offered their "Mini micro" floppy controllers, primarily for
adding high-density support to XT-class systems; they also used the
8473. I've seen a couple on eBay.
