      Yeah, that one is certainly the most outrageous. Probably also the least
      practical. Maybe that would make it the most fun. :-)

      That could work, though octal is awkward with the 1802 instruction set.
      Most opcodes have 1-of-16 commands followed by 1-of-16 registers to do
      it to.

      Maybe use split octal. Display a byte as two nibbles. Display each
      nibble as a pair of digits, 00 to 15. So an instruction like "F8"
      displays as "15.08".

      No problem! Anything that is fun and creative is worthwhile, even if
      just for its own sake. :-)
