[time-nuts] looking for low-power system for gps ntp timekeeping

[Chris Albertson]

For less money you could buy an Intel Atom board and it will run Linux and
can even act as a small file server.  The Intel board is a real Intel
64-bit CPU and it uses VERY little power, notice there is no fan on the
heat sink and it fits inside any standard PC chassis.

It has a "real" serial port and you can add up to about 4GB of RAM.  But
for this use buy a 2GB stick and boot from a small CF card, not disk.
