A Soroban Abacus Demo

[Hutchboy]

Hi,

The attached stack is a no-frills demo of a classic Soroban Abacus. I use two hidden behavior buttons for all of the 70 bead buttons [if you rename the stack you will have to relink the behaviors].

The inspiration for this was seeing an old HyperCard stack "Wild Abacus" and thought it might be a nice challenge.

Mike,

Thank you. I finally understand what abacus things do.
