For the z80? I'd sure like to see that if so.
I'll dig up the paper I wrote on it and send it off list.

Never used one, so I'm not sure how you mean here.
With an emulator, the code often resides in *RAM*.
If you don't configure the emulator to treat the
RAM *as if* it was *ROM* (ie. write protect it),
then INR M doesn't work! (well, actually, it works
the *first* time you use it, but not thereafter! :>)
Or, using INR M to 'test' flags.
Yep!
Sometimes I like the absolutely minimalist approach to
things, too. One
of these days I'm gonna dig that code out, burn it, and see how small a
z80 box I can build that'll still prove useful for all sorts of things.
I sure have enough of those parts on hand here...
I have a tiny multitasking
executive that runs in a handful of
bytes. Slick as snot -- if you adopt its coding style.
