  1. C1P Emulation - I was right!

    After some fun and games working out how to use Emacs to edit individual bytes in a binary file, I managed to change both the I/O distributor bytes in the disk image to $02 and rebooted my emulator. About 3 seconds later, I got this:-

  4. Some progress with my emulator

    Well, I've made some progress in understanding the problem, even if I'm no nearer a solution. I set a breakpoint in OS65D's generic character output subroutine, rebooted and wrote down the ASCII value in the accumulator each time it was called. I saw banners from OS65D and OSI 9 digit BASIC, a '25985 bytes free' message, an 'Ok' prompt, and a 'RUN"BEXEC*"' command.
