It's a databook (no matter how old or what company, I am sure to come
across at least one of the devices one day. For example I picked up an
RCA linear databook the other day. It's got the data sheet for the anode
driver chip used in the HP67 in it...)
Cool find! I found an old RCA data book that had what looked like the
anode driver in it but I hadn't had a chance to verify that is was indeed
the part that HP used. If it is, then that means there is some hope of
finding replacement parts.
It relates to a machine, or series of machines, that I am seriously
interested in. I'll buy all such books, no matter how elementary the
information they contain.
Ditto. I usually pick them up even if it's not a machine that I'm
immediately interested in. I pass them on to other collectors or just save
them.
It's part of a series of books that I am trying to obtain. Like the
(classic) MIT Radiation Lab series [1]
[1] For those who've not seen these, they are 28 (I
think) volumes
describing electronics, particularly for radar and radio navigation, as
it was done in the 1940s and 1950s. Lots of _great stuff_....
These are a VERY interesting series. Basicly they cover subjects that
they discovered/developed during WW II while developing RADAR, the atomic
bomb and other fancy toys. I've only been able to find one of them so far.
I think it's on Pulse Generating circuits.
Incidentally, unless I misuderstood the copyright
notice in these books,
it appears they are now public domain (it claims they will become public
domain 10 years after the date of publication, which was about 50 years
ago). I am suprised nobody has reprinted them, or scanned/OCRed them or
something.
