Any interest in "newer" hardware, software?

Thanks!  These chips were in a lot that had other digital chips that I 
was able to identify, so I thought that they were also digital. The 709 
might well be right, as it is a DIP14 package.  The other one, though, 
is a DIP16 package, and from what I've seen the ua730 only came in 8-pin 
cans, so it remains a mistery.
