   We have an IBM AT running out at an observatory, taking data
from a CCD camera via a plug-in AT card that does DMA. We'd like
to put the card into one of the slots on an RT we have.

   Can we do it? Does DMA work the same as it does on an AT?
How can we send instructions to the card, and how can we
get a range of active memory for the card to dump its data
into? 

   I'm sure that many people must have put regular PC cards
into RTs out there - we'd love to hear from anyone who has.

              Thanks in advance,
                   Michael
