Are there any other calculators besides the HP-22, HP-70 and HP-80 supporting this input method (perhaps even some featuring an EEX button as well)?

By your description I take it that this works for digits other than zero as well?

Greetings,

The HP-9815 supports this input method AND features an EEX button. Best of both world.
