The Ramkeeper will actually DMA to the card in the front
pocket, but not the one in the back pocket.  However, it
will take care of this, so you can leave DMA on.  If the
card in the front pocket is >4MB, however, then the
RamFast rev. D is the only SCSI card that can DMA to it
without problems (Apple HS and rev. C RamFast would need
DMA turned off).

The Ramkeeper will actually take two low profile 8MB
memory cards for a total of 16MB.  In this configuration,
only 8MB can be used as system ram, but you can use the
other 8MB for your ROMdisk and/or RAMdisk.  This works
with, for example, the RAM-GS+, which is very low profile.
Two RAM-GS+'s (from Sequential Systems) equipped with
8MB each would max out your Ramkeeper at 16MB.
