USB_FDD@1306

Front of board

This is an adapter for using full-size 3.5" floppy drives as USB floppy drives. It uses an unknown 24-pin TSOP/TSSOP? microcontroller. The chip has "6520" on the underside. The oscillator on the board is 12 mhz.

Note: It seems to use the sorta-compatible Shugart interface, as it uses pin 6 which is N/C in the IBM format.

for "Drive Select" it's hooked up to DS1/DS2/DS3/DS4.

Functionality

I have an identical (presumably: I need to open my case up and double-check) unit installed in my main PC. It identifies itself to windows as "TEAC USB UF000x USB Device", VID=0644 PID=0000.
