I _think_ mine says 11/20.

OK.

That's what I thought.

I remembered the OEM part. I was thinking the 11/10 came out
right after the 11/20. Perhaps you are right. That was a little
before my time. My first exposure to -11s was in 1984. We used an
11/04 to bench-test our products, an 11/24 for the accounting department
(with *4* RL02s), an 11/34a for software development (RSTS and RSX-11),
and an 11/23 or two for other purposes lost to time.

That was *many* years after the 11/20 came out.
