Actually, it boots the Amstrad core - but it comes with a risc cpu
that's also capable of running 6502 code (which is what the boot rom
is written in).

K> Do the Z80 machines require you to change the CPU card,

No.

Yes. It's actually a small RISC CPU that interprets Z80 and 6502
opcodes.

Sure, but that would take up a lot of precious space that is better
spent on graphics and sound.

No, they are SRAM based.

She's getting a ton of mail these days, I'm not sure she even reads
her old email address anymore.
