Vintage Fairchild uA709 Op Amps for anyone who wants them

I have an original bag of unused Fairchild uA709 OP Amps from 1965. These are 8-lead can's...not DIP. They've been sitting in an old tool box collecting dust, but they are unused. There's probably 50 or 100 of them in the bag. My father-in-law used to work for Fairchild back in the 60's, so this might have been something he got and forgot about.

I don't want them or know how to use. I'll probably chuck them in the trash if nobody's interested. I figure it would be useful for someone who restores vintage computers or controllers.
 
Are you located in the US? If so, I would like a few of them, mostly as nostalgia, since the 709 was the very first opamp that I ever successfully used.

Should I PM you?
 
I have surplus LEDs 5mm , very bright 200/bag.

Used many, used feed forward to get some speed out of them.

I think I have original datasheet somewhere, the initial offering Vos was 25 mV, precision......
 
Nowadays we sneer at these primitive devices, but I do recall the incredible achievement that was a MONOLITHIC opamp back in the early 1970s.

My first project with a 709 was an audio AC milivoltmeter. One would be able to measure the direct output from tape heads or phono pickups, which at the time was miraculous.
