Numpad

I’ve said that a T65 with a numeric keypad instead of a dial disc should work fine for conversion to a Wonderfoon. I still think it could work, but it does require some additional hardware because compared to the dial disc which uses two IO pins I will need five extra IO pins but there are only four more available. Enter an 8 bit I/O expander...

If this doesn’t make any sense to you: sorry...
