I can't believe the 21MX M or E user guide isn't online, but I don't see it
anywhere. You'll definitely need that book!

Hi Jay
It seems like there is some manual on Al's site that describes
the 2100 instructions. As I recall, there was nothing specifically
for the 21MX, though.
I entered a few instruction on my machine and they seemed to work.
I also looked at some of the boot ROM's and the instructions
match. I'd load the boot ROMs and then just inspect the code.
I can't recall which manual it was without checking at home.
