The links listed below are to other web sites related to HP
History. Some of the web links are moving targets. I check these
from time to time and find some of them dead only because of a
subtle change in the URL when a website was reorganized.
Here are some direct internal links to the Agilent web
Agilent Technologies and Communications: Six Decades of
Measurement Solutions This is an excellent 35 page article
about many of the classic pieces of equipment developed at HP. It
has a lot of history and is required reading. There are a few
errors that should be noted as follows. I was not looking for
errors but these stood out to me as I am familiar with these.
- The opening picture showing David Packard (standing) and
William Hewlett (with slide rule) in the garage is mirror imaged.
Proof that the picture is mirrored is obvious by looking at the
audio oscillators and noting that the output jacks appear on the
left instead of their correct place on the right. The same
picture on the HP site above is correct.
- On page 18 the upper frequency limit of the HP500A frequency
meter should be 50 kHz instead of 100 kHz. I own an HP500A and am
quite familiar with it.
- On page 20 the model number of the VHF generator in the
picture should be HP8640B. This is a simple transposition error
in the caption. I own one of these units so I am quite familiar
- On page 22 the year HP entered the oscilloscope market should
be 1956 instead of 1958 (product development actually began in
1955). The March, 1956 (Volume 7, #7) issue of the
Hewlett-Packard Journal describes the introduction of the HP130A
oscilloscope which had a 300 kHz bandwidth. The April, 1956
(Volume 7, #8) issue of the Hewlett-Packard Journal describes the
introduction of the HP150A oscilloscope which had a 10 MHz
- On page 28 the description of the HP4815A impedance meter
should show an upper frequency limit of 108 MHz instead of 500
MHz. I own an HP4815A and am quite familiar with it.
Other web sites with a variety of information: Some
of these are deep links and others may only be available
temporarily. If the web page is not found, try backing up by
deleting pages from the end until you connect to something. A
reorganization of the web site may have changed the address.
This is a great site if you are looking for information about old
radios and electronics. There are numerous links here to
just about everything involving old electronics. You could
spend hours looking at all this stuff. A related site by
the same owner is http://www.stevenjohnson.com/ and
you can find even more information including schematic diagrams,

features a personal museum and information about HP and a variety
of other equipment manufactures.
A few articles concerning the HP-Compaq
An interesting article written during the controversy over the
Compaq merger. I voted my HP shares against the merger as
it made no sense to me. I had owned Compaq stock for many
years and dumped them at a huge profit in 1999 when it looked
that Compaq had no place to go but down. I was right.
