J.J., the HP 5060 A clocks were not portable at all. They were lab
clocks, comprising four units weighting above 100 Kg., and they were
almost 90 cm high. Each one required more than 150 Watts to work.

The portable one was the HP 5061 A, but had much less stability,
precision and accuracy.


The HP 5060 A was a breakthrough in the world of atomic clocks, and
remained as the king of Cs atomic clocks for almost a decade, till late
'70s. It was the "golden years" of HP, before they entered into the
computer market, and many other instrument makers appeared, with
excelent quality (from US, Germany and Japan).
