On the x86 PC the floppy controller uses IRQ 6, on other systems other interrupt schemes may be used. »Disketten Controller«], Controller für das Diskettenlaufwerk, heute meist in dieses Laufwerk integriert. It is often also connected to a channel of the DMA controller. A single floppy disc controller (FDC) board can support up to four floppy disk drives. Asus M2N-SLI Delux Athlon 64-939 FDC only supports 1 drive. The diagram below shows an floppy disc controller which communicates with the CPU via an Industry Standard Architecture (ISA) bus. It went on sale in June 1978 at a retail price of US$495 for pre-order; it was later sold for $595 (equivalent to $2,330 in 2019) including the controller card (which can control up to two drives) and cable. Many hard disk controllers can manage more than one hard disk, as well as floppy disks and tape drives. This jumper is "don't care" if only a single drive is connected (if jumper 3 is removed). The HxC is connected to the "controller board" that I took out of an old Amiga external floppy drive. The WD1002-05 Winchester/Floppy Disk Controller (WFC) is a stand-alone, general purpose board that allov"fs a host processor to control up to three VVin­ chester 5.25-in. disk drives and four floppy 5.25-in. These are read by the CPU through this port. ECP parallel ports, SCSI host adapters, tape accelerator cards, sound card (low DMA), network cards, voice modems, hard disk controller on old PC/XT. - Yahoo! It is often also connected to a channel of the DMA controller. 5. That's too bad since my last MSI board still supported two floppies. The controller is linked to the system bus of the computer and appears as a set of I/O ports to the CPU. Unless you can build a device that acts as a floppy as seen by the floppy controller and the BIOS, which would mean something that acts as if it has one or two heads (drive controller limitation), 1024 cylinders and 63 sectors (BIOS limitation), AND reads/writes data in a format compatible with the floppy disk controller, you'll need a driver or TSR to make it appear to the OS as a storage device. Free support to any BlueDisk card owner in the A2 bulletin board on GEnie (category 46, topic 12 at this time). NorthStar sold this board as a package along with a Shugart SA-400 mini-floppy disk drive.
