• BUG: Turn off all the windows except "program", and keep entering new lines. After line 9, the line numbers for 10 and 11 will be random blobs. Apparently they didn't think people would write more than 9 lines of code, although it is possible to write larger programs as long as memory allows it (but you won’t be able to see what you’re typing beyond the 11th line).

• BUG: Put "hor1" as many times as you can on the screen until the memory runs out. Execute the "program", and then erase everything from the program and stack areas (including those square shapes in the stack). You will now have an extra byte of memory (which you can use). Repeating this procedure will give you another free byte, but it is a little unstable (sometimes clearing memory if you use it). The cart will reset itself if you try for a third! The instruction you use is unimportant, as long as the program is complete gibberish. {Kurt Howe}
