Thanks. I've used that one before, but despite the name it's an
entirely different one from the one used on RT11 for the LSI-11. They
aren't even similar.

I'll most likely write a microassembler for the CP16xx/WD21xx chipset
in Python at some point.

For another project, I'm working on a Python implementation of the
AMDASM microassembler, which was commonly used for designs based on
the Am2901, Am2903, and Am29203, though it wasn't really in any way
specific to those parts.
