Block-Bank Address Card

The M628 is a module designed for the PDP-15 system, primarily utilized within an MX15A memory multiplexer to modify address bits 03 and 04 for memory bank selection. The document outlines its technical characteristics, including: - Components: Contains two 2-position switches, a 2-bit adder, and output gating logic. - Input/Output: Details on unit load characteristics for inputs (D1, C1) and output drivers (L1, K1, L2, K2, E2, H2). - Performance: A maximum propagation delay of 100 ns. - Power: Requires 5V at a maximum of 150 mA.
