 Ive just had the Motherboard in my Amiga 2000 replaced, and found that
a 4.4 Motherboard has been installed.
 Could someone at CATS tell me ehat the changes between 4.3 and 4.4 are ?
Also could someone tell me which link causes the 0x00C00000 memory to be
mapped at 0x00080000 ?
 I know this information would be in the A500/2000 tech ref manual, but
I'm about to order one, but as i'm in the UK, it will probably take a 
long time to arrive.

 I also have the memory expansion board from an A2000 (the original Amiga2000)
populated to 1Mbyte.
 I wanted to install it in the B2000, so i disconnected link J500 on the B2000
, so as to disable the 0x00C00000 memory totally, and installed the board.
	It didnt work.
This worries me, are the A2000 and B2000 CPU slot timings that different?

	Thank you
