Mmm, or display a fixed lunar landscape showing an Apollo type lander whose vertical position is determined by the altitude figure. My original idea was to have the upper half of the VDU (Graphics) representing a changing 'view out of the porthole' and the lower half (Characters) showing the Altitude / Rate of descent / Fuel remaining as text labels / values.

Then there's that demo we talked about...

I actually think the easiest(?) genuinely fun graphic game to write for the MK14 would be 'Pong', just need to figure out how to interface a couple of analogue pots - switched up and down wouldn't 'play' right, you need to be able to whizz to about where the puck will be and then fine-adjust to return the puck in the desired direction.

Rotary encoders might be easier but they would be too 'clicky', they need to turn very smoothly.
