This list was accurate as of May 2017. Some programs may be removed in future updates to free memory for other functions. You can get a current list of available programs by setting all data switches off and press AUX1 down.
To load a program, first clear any program that may be in memory by typing “NEW” and press Enter.
Set the front panel switches 0-8 to the address of the program you want to load, with all other switches down.
Press AUX2 down, the program will start to load. When it’s done, just type “RUN” and press Enter.
(Please note: these programs can also be loaded in 4k BASIC, but most will not run due to the limitations of the language.)
