HP 21MX toggle-in programs?

[Patrick Finnegan]

So, now that I've got a pair of HP 21MX machines sitting here (thanks 
Jay!), I could use something to toggle into them to test out the memory, 
or do "nifty things" with the frontpanel lights.

I guess I could try spend some time learning HP assembly and coming up 
with things myself, but it'd be nice to have some examples to look at 
first. :)
