I hate to bust your bubble, but this machine was never released. The machine
has a CBM tape port, but the ROM has no driving code for it. Commodore's
6509-based machines were never popular to begin with & cost way to much to
manufacture, also, C= executives noticed how well the '64 was selling, and,
well, you can figure out what happened after that (wither 6509).
