Was the guidance computer on the Surveyor spacecraft the same as on the Apollo lunar module?

The computers were of totally different architectures, produced by separate companies with different capabilities.

The Surveyor system is much simpler as Surveyor made a direct-from-Earth, almost vertical landing.

Apollo's computer had to deal with range and descent from lunar orbit, which is much more complex.
