Working on some interfacing experiments. They come from a book called "Interfacing & digital experiments with your apple" by Charles Engelsher. It requires me to load both an assembly program and applesoft program at the same time. The applesoft program calls the assembly program as a sub routine. I wrote the assembly program using Lisa v2.5. Can't figure out how to back out of Lisa once the binary is loaded and lauch the applesoft program??? If I try to load the assembly program outside of Lisa I get a file type error message. Could I be getting tripped up by two different versions of Dos? I am working in Dos 3.3. When I boot from my Lisa disk I don't see any indication of what version of Dos it is running?
Any suggestions are much appreciated. Thanks, Chris
