I hadn't noticed that. I'll have to view the video again. Morris will
probably tell us what's going on.

It is uC driven, and can count upto 30KHz. Its quite possible, that
Morris is pulsing quickly (faster than we can see) from 0 to 1 to 2.
Then more slowly from 2 thru 9. Reset to 0, followed by a slow 1 and
2. The cycle then repeats.

The count following, 9 will be the 11th "carry" position, were the
carry signal is generated. In older circuits for this tube, that carry
usually also generates a reset pulse. To get better control, that
signal could be routed to a uC input, and a separate uC output goes to
the tube's reset input. Level shifting circuitry implied. Of course,
only Morris knows for sure.
