The usual technique was to zero HL, and DAD (Double Add) SP to HL to
get the value to save.  A bit clumsy, but hardly impossible.  If you
were doing a task switch, you had to be sure to save the PSW first,
since that sequence would alter some flags (and obviously HL).

I don't remember that the Z-80 made that any more direct (although
there were more variations of the same approach - more options for the
source register when loading SP, and more options for the Double-Add*
target).  But I may not be remembering it, very little of what I did
on 8080/Z-80 systems was allowed to use the Z-80 extensions.


*Allowing that for Z-80 assembly, the DAD mnemonic was replaced with a
form of ADD.
