Look. If you don't want to call it a Z80 processor, then don't. No
one here says you _HAVE_ to.
Of course, no one says you have to call it a TI-85, either. You
could call it a microcomputer. (And _DON'T_ tell us it's NOT a
mocrocomputer; it has a microprocessor, RAM, ROM, and i/o devices.
That _DOES_ qualify it as a microcomputer.)
>How do you know that it has exactly the same insturctions?
We HAVE documentation to prove it. Also, try writing a program for
it. I'd think that should prove this...
Undoucmented commands were previously discussed on this list. Check
out the List-ZShell Archives at www.TICalc.org.

True. You need to know: A WORD is always two (2) bytes, or sixteen
(16) bits. A BYTE is always eight (8) bits.
This Z80 Processor uses 16 bit addressing and 8 bit data processing,
if that is what you mean.
