Just thinking out loud. The 'mite has a PS2 keyboard interface. A PS2 keyboard has like 100 keys. Thats 100 digital inputs, accessible with the INKEY$ command.

Is there a PS2 encoding chip, that can take switch or digital inputs and send out PS2 serial data, for connection to a Maximite.

It would give us a lot of extra digital on/off inputs, say for monitoring, etc, and means we still have the 20 odd 'mite pins to control and sense analogue, duration, etc.

One application would be a custom built ( and compact ) keyboard, with say 12 keys, instead of a full sized keyboard.
