Very creative use of it. How did you get over the I/O hurdle? I never did find working instructions for saving BASIC programs to disk; lots that didn't work, but none that did, and none that even explained what they were even trying to do... It stymied me for years. It's only now, with access to the modern internet, that I've found out why files on the Commodore were so strange: Disk I/O was neither raw, nor handled by the BIOS, Commodore had it's own unique solution. Drives were their own self-contained computers that communicated with the C64 in a weird and proprietary mini-language that was passed to it from BASIC I/O statements nearly raw.
