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
maximum clock speed and OEM volume pricing information on parts such as 7473
thru 79 or 74106-116? 

I must be getting old because I remember the 7474 well but I thru out my
Yellow books years ago :-)
