Quoting Niklas Ramsberg <email@example.com>: Howdy Nicklas, I found that problem with certain of the cartridge expansion boards when I switched from a C=64 and upgraded to a C=128. Earlier or some brands seem to want to boot a C=128 into 64 mode no matter what unless you turn the board off. It was an unbranded brown expansion board with a fuse on the end and a red square reset button. When I switched to a CMD expansion board, the problem went away and could use in in 64 or 128 mode. Anyone else run into this problem with some expansion boards?
