Friden 1152 Operator's Manual

This document is the user reference manual for the Friden 1152 programmable electronic calculator.

The Friden 1152 is essentially the same as the Friden 1151, but adds a one-key automatic square root function. The 1152 uses a mix of small and medium-scale DTL and TTL logic IC logic, combined with a magnetostrictive delay line for the register storage.
