8" Floppy Drive 34-to-50 Pin Adapter
Sold by RetroDisks
This is an adapter that enables 3.5" or 5.25" floppy drives to connect to systems designed for 8" floppy drives. It bridges compatibility between smaller floppy formats and controllers intended for 8" drives.
The board supports features such as selectable double-sided detection, flexible motor control schemes, and drive select remapping, with labeled signals for easier debugging. Setup involves configuring jumpers (JP1–JP4) for media type, motor behavior, and density, and optionally modifying resistor pads to match the target system’s drive select requirements.
Original project 'fd50to34' linked below - did a run of these for a personal project an have a few leftover.
