The QuadFlop is a four-port ISA based floppy controller which has some additional features not found on other controllers. It has a built-in display to show drive activity which can be removed from the card, and mounted remotely. It also has a microcontroller installed to send TG43 information automatically to 8″ floppy drives which need this support.
