[time-nuts] HP Stories: Frequency Counter business

[Dave M]

More likely, the counter Neville used was the model 524B (see picture 
attached).  The 525 was a series of frequency converters that enabled the 
524 counter to measure frequencies up to 500 MHz (Megacycles (Mc) in the 
vernacular of the time).
Surely is good to learn about the beginnings of the HP culture and saddening 
to hear of the hard times that have befallen, but technology never stands 
still..
