Armonk is corporate headquarters for ibm, not yorktown heights.Yorktown heights is 17 miles away.
Yes. I goofed.
I had a college friend who lived in Yorktown Heights, and his Dad worked in R&D for IBM.
Did IBM have a chip fab in Yorktown Heights in the 1960s-70s?
My friend's Dad only drove a couple a miles to work, and he worked in a very large facility.
