- Little Tower; the first (?) adventure game for the Apple-1 by Arnaud Verhille. Discovered that there is a broken version of this game haunting the Internet, two-word commands where not processed. A fix is in the description. You need the 1000-1FFF memory area as well in order to play it.
- Lunar Lander (ASCII Graphics); changed to the correct version including sound effects by Corey Cohen. To start the game in the emulator, you have to disable the sound first, instructions in the description.
- Peg Solitaire; remove pegs by jumping over them and clear the board, again by Jeff Jetton.
- Cat; nice artwork by Denis Paryshev.
- Mandelbrot 65; draw the well-known fractal structures while heating up your room, by Frederic Stark. You need the 1000-1FFF memory area as well. See also my comment here, it seems that the latest version on GitHub is not running on an Apple-1.
- Twinkle Twinkle Little Star; a BASIC program that uses the ACI to output some music, by Corey Cohen. Instructions on how to make your own songs are in the description and in his BASIC source code.
- ASCII HEX; two routines to display the ASCII Hex equivalent of a character by Arthur L. Schawlow from 1978.
- Memory Test; by Mike Willegal, added a version to test the memory range of 1000-1FFF.
- Stopwatch; keep track of the time or use it as a stopwatch. Program in BASIC by Larry Nelson, Bob Huelsdonk and Val Golding from 1978. Did not get it to work properly on my Apple-1, added some comments here.
- TypeWriter; a small program created by Landon Smith, he used it to test his early Apple-1 emulator.
