So unless it's wrong, it doesn't make sense to dump any other pages than 8 to F. Unassigned space will read whatever is on the bus at that moment (like reading unassigned space in the C64) and the RAM and I/O contents don't matter. Page 0 and 1 are most likely the 64 Bytes RAM mirrored multiple times. Gerrit Message was sent through the cbm-hackers mailing listReceived on 2014-07-05 17:00:39
