I'm with Tony on keeping old data books. In our shop we service
everything coin operated from around 1900 and later. I have tube and
thyrotron books from the 1930s through 60s, catalogs on magnetic memory
cores (used in Seeburg jukeboxes in the mid-50s through mid 70s), early
transistor books (late 50s), then digital logic books starting with RTL
and early TTL (eg. TI - Designing with TLL ICs - 1971)...
I could post a list of my manuals, but then people would bug me for
reprints of various chips and I'd get no work done!

For some
Computer History Museum work I need information on 7400 series Flip
Flops (S and Normal, DIPs) circa 1973 (anything 1970-75). Anyone have any
I have a 1978 TI TTL databook to hand, if you think that would be any
use. It would have the spcs for the devices you mention (but I suppose
they might have improved them between 1973 and 1978).
maximum clock speed and OEM volume pricing
information on parts such as 7473
thru 79 or 74106-116?
I won't have OEM pricing information, alas. I might be able to find old
adverts selling 1-offs to hobbyists, but that's all.
I must be getting old because I remember the 7474
well but I thru out my
Yellow books years ago :-)
I've kept all my old databooks. Darn it, I need them.. I use them
virtually every day (for design and repair...)
