For the sake of anyone on the list who's interested, I've made up two 
simple programs to test my ability to comprehend the manuals. :)

I'm sure they're probably not the most efficient way to do it, but they 
were the best I could do in a couple hours, starting from zero HP 
assembly language knowledge. :)  Also, I'm sure I'll add to it as I 
spend more time playing with the machine.
