@garyg Communicating with AmigaKit is always a bit hit and miss. I guess it is because they are very busy and have a lot resting on their shoulders.
I hope to have a CD32 compatible Joystick Switcher (or two) one day as the product is listed on their website (Ref: JOYMSESW2) and I've been told by them that they have the unpopulated boards but it's over a year since I enquired about the product's availability going forwards and it just seems to sit on the back-burner forever! :-(
I'm just paranoid about burning out my CIA chips at an Amiga meeting by hot swapping CD32 pads and mice! I hope to have their availability firmed up someday and to have some assurance that they'd contact me if they did become available. Still waiting. :-(
