By the way, an idea just popped into my mind...
For the Z180 CPU, eventually also an 'emulation' TSR could be made, which
emulates the Z380 through 'trapping' of illegal opcodes. It will be _really_
slow though...
I am wondering... Do the registers IXh IXl IYh and IYl really exist on the
Z180??? I doubt it, because otherwise their locations at least should have
been indicated (otherwise the usage of trapping on an undocumented
instruction will be very confusing since it does not work).
Or will those registers be emulated through trapping???
That will be slow (but it'll work, and as long as the instructions aren't
used it is still fast) (might cause some -a lot, in fact- incompatibility
issues with programs using them)...
I'll read the entire 'trapping' docs... See what the possibilities are.
Will come back at it later.
