Guilty.  And a couple of sbc makers.

Right, 32Mb of rtlinux and the EMC - sans gui on a compact-flash.  And it
would be a great black box with just a power cord, an ethernet connection,
and with some of gecko's finest, molex connectors for each axis.

Of course you could make it just a netboot and have no hard storage.  128
Mg 100 sdram is going for < $50 now.  Compact Flash is close to $100.

Thanks for the links.  Anyone up for making one or two of these work and
display them at NAMES.  I can build them here if I can get help with the
software setup for it.  We could use an industrial sbc or a cheapo board. 

I'd like to see the project details preserved as "open pages."  We could
GPLD them and put them in a section on linuxcnc.org.
