I just wrote a stop watch program this weekend. Sorry, timer interrupts
are turned off while the calc is off, to preserve power. However, around
normal room temp conditions, etc. it works pretty well. By the way, it is a
zshell interrupt program that uses the graph memory. I'm going to post it
soon. It would be useful inside a program as a game event timer. It could be
loaded just like a grayscale interrupt, or along with a grayscale int,
although some adjustments would have to be made.
Also, on a side note, the speed of the whole calculator is going to change
depending on the above conditions.
