This is a look at the EXM-13, EXM-13A, and EXM-13B.
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.
If you have any files or experience with these devices, please reach to
Louis Ohland.
