RTL had a much wider supply range, IIRC.

Hi Chuck
The RTL I played with was quite fussy about voltage.
It wanted 3.6V. 4V or more and it didn'y work.
I made a digal dice ( that I still have someplace )
It used JK's but I forget what I used for an oscillator.
I had it in one of those clear plastic picture cubes and
used mercury switches to detect the roll. A 9V with
something to regulate ( forget what ).
It went through the 9V battery faster than one could
play a game of monopoly so it wasn't much use.
Display was small LEDs.
