Description

Amiga DFO and External Floppy Swapper v2.1-b (floppy side)

This module can swap an internal DF0: drive with an external DF1: floppy drive in order to boot from an external device, such as a Gotek Floppy Emulator.

First module (other) fits under the MOS 8520 Even CIA.

Second module (thus one) is inline with the internal DF0: drive. (See other project)

A small CPU detects two fast consecutive resets (CTRL-A-A twice). This will activate or deactivate the floppy swapping.

A piezo will emit sounds when the swapping is activated or deactivated.

This device will fully support external booting from any 880K disks, while still permitting the use of internal DF0: as DF1: (hardware fix)
