A couple more questions for my A500T project..

[rkauer]

 1- Probably not, the 1200 is some kind different, I think. Use the original keyboard, instead (or one taken from an A2k/3k/4k).

 2- Not without a Buster (A500 don't have it) to control more than one Zorro slot;

 3- Yes, with a clockport you will be able to connect a Delfina to your A500 (IIRC, someone here in A.org had do it).

 For the A2000...4000 keyboard: it is just a matter of wiring the 4 wires from the A500 mobo for a DIN connector.
