Hello to All,
I am doing experiments with my Apple-1 ARM Replica, and after a lot of work on the ACI driver, I can save and load programs and data into real tape cassette. While working on this driver I tried to generate some sound, as if the ACI was a sound card. It was so fun that I developed a tiny music player with a simple tone generator and a note sequencer. The first music I tried to compose is the theme of the movie "Back to the future"
In attachment you can ear te sample taken directly from my emulator. I am pretty happy but I will be real happy if this worked also on a real hardware. So is there somebody who wants to try this for me?
The program saved hopefully should load also on the real hardware by typing:
and then launch the song typing:
You should hear the music...
The main program starts at 300, even if there are parameters and variables starting at 277. Music data starts from 400, and every note is a group of 5 bytes. Pauses are treated as notes as well but without toggling the output line. If this works also on the real hardware I will put the assembly source code online of course. Who knows maybe this gives a new life to Apple-1
Thank you all!
