Contrary to rumours the Beebugsoft version of Moonlander will run on a 16k machine, but you must type PAGE=&B00 (RETURN) before loading it.

Astrotracker has a facility to alter the colours used. This is achieved as follows: alter line 1198 of the header program to 1198 ?&8E=f:?&8F=b where f and b are numbers between 0 and 7 representing the colour of the foreground and background respectively. See Beebug reference card for details. The flashing colours have no effect.
