I gather that IBM makes an expanded memory card known as an XMA, and sells
it mostly to people who have 3270 PCs.  (It was apparently the solution to
the problem that the resident code for the 3270 emulaton system takes up
about 639 1/2 K.)

The usual technical reference manuals are silent on the topic of how the
XMA card works.  Does anybody know?  Has anybody actually programmed one?
There is some speculation that it might be sufficiently similar to an
Above Board that we could easily mutate some Above Board code to deal with
one.

Any help would be appreciated.
