My reference was to the Prometheus board that was suggested, and it does
look like a viable source for the data acquisition.

Actually, no, you referenced my post about the Athena. Anyway, that's just
a quibble.

I have not looked up the Athena. Who makes it?

Diamond Systems. Same as the Prometheus. The Prometheus is actually pretty
old. They also make the Hercules, which won't fit in a standard PC/104 stack
chassis, but it has enough I/O on it that you probably wouldn't need to add
much of anything to it.

Even the 128mb is pretty marginal for Linux except possibly in the
straight data acquisition mode.

Most every display I've ever put or seen in an airplane has way less (by an
order of magnitude) memory that that. If you're hitting the wall for an
airplane display with 128mb, then you really need to rethink about how
you're running it. Maybe a stripped-down kernel just driving OpenGL stuff
makes more sense. A full-up Linux installation doesn't make much sense for
use in an airplane.
