Question - How could you have saved Magnavox Odyssey II ( more commonly written as "Magnavox Odyssey²" ) programs to cassette ?
- I am basing my question on saving programs written using using the cheap "Computer Intro!" cartridge, so I assume that would rule out using cartridge pins as I/O .
- NOTE - I am not aware of there being any other way to write programs on this machine, other than by using the "Computer Intro!" cartridge .
- My question DOES NOT involve using the "C7420 Home Computer Module", and anyway, this was only available for the Videopac+ and the Jopac consoles .
- Note - There obviously seems to be no easy way to connect this machine to a cassette-recorder .
I never had this machine, it's just to see if anyone thought of an easier or more practical way than my ideas .
. . ( The more I think about it, the less worthwhile my question becomes, due to the bad quality keyboard etc, but it's such an early machine that it seems worthwhile . )
My broad idea for saving a program, is to somehow make the computer emit a different audio code, like binary or something ( or, maybe frequency, but doubt it ) for each text character, when a program is listed, or when it is typed, and then run a cable from the TV earphone plug to the cassette-recorder.
. And to load a program, you would of had to connect wires from the cassette-player to the internal wiring for the keyboard, to simulate typing, but since I doubt this keyboard functions in a way to allow this, maybe connect wires from the cassette-player to the joystick or cartridge port pins ( which unfortunately are occupied by the "Computer Intro!" cartridge ) .
Another method for saving a program may have been to make a flashing-square somewhere on the screen that flashed different codes for different text characters when they are typed or when the program is listed, and put a photodiode ( or something similar ) right next to the flashing-square, and attach a cable from the photodiode to a cassette-recorder .
