- Implemented initial version of extended memory support, which allows the EightBall source code to be stored in aux RAM (extended 80 column card). Once an apparent bug in the cc65 extended memory driver is fixed then bytecode will also be stored in aux RAM. - Moved non-performance critical portions of interpreter / compiler to Apple II language card memory, which frees up more main memory. - Improvements to display of free memory (`free` command)
