Control Data (?) circuit boards

Speaking of Control Data:

I have some boards out of (AFAIR) a Control Data 
Display Controller (OSG 1253/1255), each populated 
with ~30 10pin TO-5 ICs; they're Fairchild with 
(house?) numbers such as 115, 116, 117, 118 and 
what I assume to be date codes (all 3 digits, 
7xx), e.g. F 115 728.

Any reason why I shouldn't scrap these (after 
cutting off the gold fingers of course ;-) ?
