Data Selector M1701

This document is a technical schematic for a Digital Equipment Corporation "Data Selector M1701" circuit board.

Summary: The schematic details the layout of two DEC 74153 integrated circuits (E1 and E2). Each IC is configured to accept data inputs, address lines, and strobe signals to produce specific outputs (F2, D2, P2, and M2). The board includes a power supply section with a 6.8µF 35V capacitor (C1) connected to a +5V rail, with additional capacitor mounting points (C2, C3, C4) for filtering. The document also specifies that, unless otherwise noted, capacitors are 0.01µF, 100V, 20% tolerance, and that the integrated circuits used are DEC 74153 models. The schematic is marked as "furnished only for test and maintenance purposes" and carries a 1970 copyright.
