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

[Chris Albertson]

For a NTP use the $40 ARM.   The Atom is going to pull maybe 10W of power
but can do a lot more.  I just did not see the use of the $90 quad core
ARM.  It is over kill for NTP

I  had my Atom running NTP, file server and inside a VMware virtual machine
Lady Heather to monitor the Thunderbolt GPS.  The Atom was headless so the
LH display screen was exported to one of the other computers when needed.

Related Topic:   It would be great to run LH on an ARM and not need to have
to keep a PC running, even if the PC is an Atom running a virtual PC.
