Cassette Interface

This document consists of the technical documentation, parts list, and schematic diagrams for a Digital Equipment Corporation "Cassette Interface" circuit board (M8331-0-1).

• Page 1 provides a physical layout of the printed circuit board, including a component placement map, a detailed parts list (listing integrated circuits, resistors, capacitors, and hardware), and a jumper configuration table.
• Page 2 contains the logic schematic for the interface's control and command processing, detailing the connections for various "I/O" and "Write/Read" control signals.
• Page 3 provides the schematic for the status and data register logic, including the status registers, read/write buffers, and the associated logic gates used to manage input/output data flow for the cassette drive.
