I doubt it. I think someone wrote to Bil Herd complaining when the plus 4 had a machine code monitor added and said something along the lines of "you've made piracy really easy" & he claimed to write back saying "thanks". C64 autoboot cartridges start in C64 mode, because they need to autoboot and they won't work in C128 mode. > Interesting. One hand doesen't know what the other is doing? :) If the z80 detects the commodore key, then it puts it straight into c64 mode & doesn't repeat the check. It might just be left over, or they may have wanted to keep z80 and 8502 soft resets consistent.Received on 2018-06-07 14:02:25
