I have written many things in Z-80, (Lisp system, Disk debuger...)
and I have never run across a documentable `POPI'.  If you are up
on your undocumented instrutions, this almost looks like a canidate,
but if you think about it, there are no 8-bit pops, or pushes.
[elaboration:  If you could `POP H' or `POP L', then you probably
could `POP I' (the `I' of IX), or `POP I' (the `I' of IY). ]
I  think you might of meant `POP IY'.?    Good disclaimer...
