There were two schools of Z80 for Apple II.  Cards like the SoftCard make up
about 99% of them, and are essentially processor only cards, relying fully on
the resources of the system.  This limited the card speed to 1Mhz because
thats what all the system resources are running at.

The alternative was more a system on a card, PCPI Applicard, I think there
were two other brands on the same card. Which run at some ~6Mhz Z80 and
support their own 64-128k RAM on board, with possible RAM expansion.

Personally I prefer the latter, as the on board RAM can also be accessed from
the 6502 side of life.

Apprently at the time CP/M on the A2 was popular with your secretary types
with WordStar.
