This is a look at the EXM-13, EXM-13A, and EXM-13B
EMC - Embedded Modular Computer
EPC - Embedded Personal
EXM - EXpansion Module
One EXM of note is the EXM-13A, based on the NCR / Symbios
Logic 77C22E+... We do have Radisys drivers, but that chip
is shrouded in mystery... NT4 does have ncr77c22.sys, which
MIGHT work, but I do not know the color depth.
Notice: I have NO
personal experience with any Radisys EXM related system or
components. All these files were retrieved via Internet
Archive and were re-named to a shorter format. To me, there
can only be one period in a file name, or you may get odd
problems with web pages...
Use of any of the files or information on this page is
AT YOUR OWN RISK. If you want
a guarantee on this stuff, seek out any repair / service
company that supports EXM / EPC devices.

Warning! Some EXM
modules are incompatible with other modules or carriers.
Please read the documentation from Radisys. Do NOT assume
the EXM format module is compatible in your application!
