The next question: is there some sort of 'user guide' that shows how to
operate the frontpanel to deposit/examine values in memory, etc? I've
figured out how to get the program counter, and step through
instructions (and the run/halt switch), but don't really know what the
other registers/stuff is.

Thanks. :)
