Amiga A500 / A2000 boot selector

This device swaps the DF0 and DF1 signals and allows you to boot from a secondary drive. It works with GOTEK / HxC floppy drive emulators and the original Amiga floppy drives.

Our Amiga 500/2000 boot selector design is a bit different than those available on the market nowadays. It uses a multiplexer to swap proper signals. This solution is therefore not prone to errors that can cause instabilities due to signals going from Even CIA to a switch and back to Even CIA which is commonly seen in other solutions offered on the market. It basically grounds (or not) a signal going to a multiplexer instead of Even CIA.

Installation

This is a plug and play solution. No soldering required.

1. Remove the Even CIA chip (look for 8520A) from the motherboard.
2. Insert a boot selector into the socket you have just removed CIA chip from.
3. Install Even CIA into the socket of the boot selector.
4. Install a switch in the location of your choice and plug the cables into the pin header on the device (the cable positions are interchangeable).

Remember to check boot selector and CIA chip pin 1 orientation while installing.
