I have compiled a collection of System 1 Applications mostly taken from the User's Manual but from other sources as well. In order to make loading them easier I have also written a python application that converts a raw binary file (.bin) to a .wav file that can be 'played' into your System 1 - bin2wav.py, it will also generate System 2/Atom format files.
I use the ca65 assembler and so have compiled the applications in that format and here they are:
I have also produced a System1 Monitor EPROM image that includes all these applications as well this can be found on the System 1 Monitor page.
If anybody has any more System 1 applications then I'm happy to add them.
