Thanks G, no moonlanding in that one but found it at

Its the same - freefall all the way, no control of the engine at all.
I've tried quite a few versions now on the 'big' & 'little' PIC14s including one from Doug Rice's page and I'm beginning to wonder if we've stumbled across a whoopsie with the PIC portA keypad port read... if I manually patch in higher thrust values at F1D it responds, and will climb with thrust at 8 until the fuel runs out!
... yet Duckshoot, which also does simultaneous screen and keypad, works perfectly!
Hopefully someone with a PIC14 can give it a try...
Cheers
Phil
