[time-nuts] HP 10811 vs HP 10544A

[Bjorn Gabrielsson]

Hejsan Flemming,

The old timebase was a TCXO on a small board sitting in the same slot,
where the OCXO now is. Its an 5342A Microwave Counter. Not really
perfect for high resolution 10MHz work. I do have manuals for the
5342A and the old 5328A - should anyone need information about above
models.
