Clock Card for my Apple lle. Installed a couple new batteries. Downloaded archive image and created Floppy, and good to go.
With no battery for awhile it displayed Jan 35 as the date.
This is from a cassette from 1979. It is what it says. Paddle controls your sub at bottom of screen. Different values for each ship type.
I listed the basic program and made a few code changes. I added more ranks, time in game, and higher score values. I converted cassette file to disk image from which I made a floppy. Run on IIe and my IIGS.
