There were some differences in reset signal between various Amigas, sorry can't remember exactly which now.

Big box Amigas handle the reset on the motherboard, the A500 handles reset in the keyboard itself.

You can convert an A500 keyboard to big box by removing transistor Q1. And vice versa, of course, if you happen to have the right kind of big box kbd. There are many revisions.

As someone mentioned, the CD32 keyboard port (labelled 'aux') is the same as the A4000 port (desktop at least - never had a 4000T).

The T has a 5-pin DIN like the a2k/3k

I wonder why?  The 4000T was an AT machine wasn't it?  Maybe that's got something to do with it.


AT as in Amiga Technologies or fitting a PC/AT case?

C= made them too, but not many. Amiga Techonologies made more.

I'd say it's because of the PC/AT compatible case.. AT motherboards used the 5-pin DIN too.
