Logic Schematic for Friden 1162

This is a logic-level schematic for the Friden 1162. The schematic includes all of the logic for the calculator at the gate and flip-flop level. The schematic was derived from The schematic only includes the circuitry located on the plug-in circuit boards, and does not include the power supply.

The numbers preceded by an "M" inside the logic symbols indicates the board number and IC package on the board in which the logic element exists. The first digit after the "M" indicates the board number, and the next two digits indicate the package number on the board. Packages are numbered beginning at 1, starting at the lower left-hand corner of the circuit board, moving horizontally across the board with the package number sequentially incrementing, moving row at a time, left to right, through the package at the upper-most right-most point on the board. In general, the package number is identified by etched notations on the circuit board near each package. For example, M304, is on board #3, and is the 4th package on the board, which is the "D Counter" IC, SN1288.
