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

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...)
