I tried to mail this, but it bounced.  I hope it is of enough general interest
that it is not a waste of bandwidth to post it here.

I know the Master I have is 2.2, but off hand I could not tell you if there is
further version info (I think it may be 2.2B, though).

OK, my understanding is that CP/M 2.2 gives you 56K of usable space.  If there
is an Apple version of CP/M 3.0, that should give 60K of work space (out
of 64Kof memory).  To access more requires a different BIOS, I believe.
 I know that
some of the Z280 systems have 512K system memory, but I don't know of anything
for the Apple (I still use a II+).  I thought about getting an AE Ramfactor
board several years ago, until I found out that to use it under CP/M, I would
have to purchase their Z80 board as well (which came with CP/M 4.0 or 5.0, or
some such animal).

I don't know if Z-System would be able to take advantage of additional memory
or not.  I just recently started looking into the product.
