[sdiy] Mysterious can IC's

[Aaron Lanterman]

Hi gang,

I'm sorting through the big pile of parts inherited from my grandpa.

I now have tons of little plastic baggies labeled with various transistors 
and IC's and such. One I get things somewhat coherent, I'll post a list to 
see if there's anything anyone needs. (I had someone interested in the 
2n229's - but we figured it would be best if we wait until we see if 
there's anything else they need to make the shipping worthwhile). And, 
I've really just started sorting through it...

I have a set of mysterious toldstool like circular ICs. They're black, 
with rounded tops, and they have 8 pins. They have a labelling that looks 
like an italics f, then a micro symbol, followed by a capitol L, and the 
numbers:

91428-6926 (3x)
91428-6934 (5x)
91428-6616
90028-731

Oh, and here's one that's not black, it's shiny, looks more like a 
standard metal can. Labeled ful 29729-708.

any clue what these could be?

Ah, here's a metal can, shiny, 10 leads, marked with a bold S and then the 
numbers 7409, and under that it says "WE3141"

Here's another metal can, shiny, 10 leads, says "TAA" and "293" under that 
and then "D66AT" under that.

Mysteries upon mysteries...
