Lines: 23 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 Richard Almeida rpa@uk.ac.ukc !mcvax!ukc!rpa rpa@ukc.UUCP
