I'm pretty sure that Sargon II was much stronger than that.
In 1980 I had access to a TRS-80 model I and Sargon II and I was very impressed
by the strength of the program.
I'm sure it was at least 1650 elo, if not 1700.

You mean that Sargon I was using a SEE?
Because as far as I know Sargon II and the next versions were not. They were
using a real QSearch instead, which made them much stronger.
