The Eiffel 3 is a great add on to the Atari ST if you are wanting to connect a PC PS/2 style keyboard to the ST.

I didn't have any PS/2 keyboards knocking around at home but there are USB to PS/2 adaptors available to use USB keyboards and mouse.
They work fine but they look cumbersome connected to the Eiffel 3 - seems to mess with my OCD for neatness.
So I am going to remove the mouse and keyboard PS/2 sockets and replace with USB ones.
Below is the pin out and connections required to get this to work. Unfortunately it's not a drop in de-solder / re-solder job even though the pins marry up.
EDIT: This the correct pin to pin photo
So a bit of hackery is needed
