Geoff, can you key in this version of the cylon program and see if it works?

Yep, it works fine.

The only reason I used Positive Non-Zero on the unconditional jump was because the last 3 bits of the instruction must not be less than 003, so I just set them to 007. Any value 003 or greater will work.
