So I have a SONY MPF720-2 slimline drive that I want to connect to the external floppy port on my A1200.

The connection on the board looks like this.

With a large connector, presumably a specific IBM thing to allow many connections.

With this connection to the cable.
https://drive.google.com/file/d/1XE-...ew?usp=sharing

My goal here is to trace out the cable and then wire it up to a 23 pin connector.

My main questions here are, what specific things will I need to do to the drive before connection.
Also with the drive select 1,2 or 3, is there some logic that is needed at the drive end, so it responds to the select.
I also assume there is a specific way that the Amiga knows that there is another drive connected an what number it is.

Any light anyone can shed on this?
