They do indeed. There is an "oven ready" light on the HP's front panel
and a large fibreglas-wrapped object taking up much of the space inside
the box.
The Motorola device has no NMEA output, but can produce 2.5, 5, 10,
12.5, or 25MHz reference frequencies depending on jumper settings inside
the box.
I wish I had a use for them. Right now they're just another piece of
the junk piled up in my garage. I use the NTP-syncronized clocks in
my computers as my primary time reference because they're on all the
time anyway.
