What's the different' Between 3640, Revision 3.0,3.1 and 3.2

[amiga1084]

Hello All,

I've had many A4000 and two A4000T  with either 3.0 or 3.1 3640 boards.
But I have never seen revision 3.2. Both my A4000T came with revision  3.1.

So what I would like to know, is revision  3.2 the best. If so why didn't ESCOM put in there A4000T  instead  revision  3.1 3640 of the Commodore board?

Like to here ouyr comments.

Thanks in advance.
