The ink is too faded to have it show-up in a picture.
It's not Harris (unless they had an earlier logo with a lightning bolt instead of a waveform).
This is a curiosity thing for me.
I thought I got-in on the ground floor when TTL was the big to-do in the early 1970's
I used to know all of the up and coming companies back then. Then they started merging and
going belly-up and new start-ups took off. About 10 years ago I called Fairchild (which changed
hands somewhere along the line), and they swore they never made the diode (with the Fairchild
logo on it). I realized I was talking to people who weren't even born when that diode was made.
During the restructuring of the company, the new owners apparently just destroyed all of the old
data sheets because the parts weren't being made any more.
So much for internet searches of 1960's/70's electronic manufacturers that don't exist any more.
Thanks for giving my search a shot, Delta Prime & kellys_eye.
Those old companies probably aren't of much interest to anybody nowadays (except me, who
still has parts from that era). I can read the component identification fine, I was just curious
about who made it. (Just like that 'ID' TO-3 package I asked about in an earlier post)
.... I don't think it's dementia yet, just a lot of years of not seeing some of these logos in a long time.
