I have a Z-248, and I use a BocaRam AT card from Boca Research.  It works fine
in the 248 as long as you use 120ns or faster ram chips.  The first two rows
of chips can be 64K, to bring base memory to 640K (I use it this way in my
machine).  The remaining take 256K chips and can either be used for EMS or
Extended memory (2Mb total, or 1.5Mb if you use the first two banks for 64K
chips).

The EMS driver supplied with mine is 3.xx.  Does anybody know where to get a
4.0 driver for it?

Oh, if you need more memory, there is also a daughterboard available for it.
Adds another 2Mb.  The card is also a normal XT card (except for the AT buss
connector) so if anyone out there has an AT board in an XT case it will fit.
