# RPNZL Users Manual

The RPNZL Programming System has been designed to provide an alternative environment for the 2X80, ZX81, TS1000, and TS1500 computers. This design was carried out with four primary purposes:

1. to increase the speed of program execution;
2. to reduce program and data memory requirements;
3. to give greater access to the hardware; and
4. to be simple enough to be hand-compiled (for development) without sacrificing the above features.
