Why would you do this?

The rev6a can be upgraded to 2MiB chip RAM by simply replacing the Agnus (Doesn't have to be an A3000 Agnus it can be 2MiB 8375 Agnus), changing some jumpers and replacing the 1MiB RAM with 2MiB RAM on the motherboard.

If you want to reverse it you put the jumpers back, swap the Agnus and the RAM.
