Thanks for the heads up. I too enjoyed working on the Apple ][. My daughters school was given one by Apple back when she was the first Kindergartner in the Stockton Unified Gifted and Talented program. They decided that the GATE class was the perfect classroom to get the computer. . . but they had no software. I spent a lot of time writing software for it. . . and the school let me take it home to work on it.
I recall one night after spending twelve hours writing a spelling drill program for the teacher that would show a picture of the object to be spelled and providing other clues, it allowed the student to try to spell it correctly. Pretty nifty. When I went to save the program to floppy, the bleeping computer claimed it couldn't find the floppy drive. On an Apple ][ of the period, the only way to get one to re-recognize a floppy drive, was to RESTART the bleeping computer. . . losing all your work. I could not save all my work.
The blue invective awoke my wife at the other end of the house and probably neighbors for at least a couple of blocks around! That was the day I learned to make incremental saves on anything I was doing. LOL!
I learned about incremental saves, too ... back in the day ... :-) ...
But even today, I’m still telling a few people here and there about incremental saves. A few times of typing a long e-mail on Yahoo and losing it, will make you a believer!
Too bad we didn't know each other back then. I could have helped you. If the floppy isn't recognized, drop into the monitor program. Connect a tape recorder (any will do). Issue the appropriate save commands in the monitor, to save the program to tape. After reboot, reload the tape, then save to floppy disc. On my Apple II I started with cassette tape saves, because disc drives weren't available for another year or more. I can still load programs off the Internet by connecting audio to my Apple II (still works after 37 years).
