Loading Instructions
To load and run the programs, place the cassette in the cassette recorder, type, for example:
CHAIN "MOUNTS"
and press RETURN; the "Searching" message should appear on the screen as you do this. Now press the PLAY button on the cassette recorder and wait for the program to load. Each program will take less than one minute to load, assuming the cassette is wound on to the appropriate position.
