G207

This document is a proprietary circuit schematic diagram titled "INHIBIT DRIVER G207," designed by Digital Equipment Corporation (DEC) and copyrighted in 1965. It is provided for test and maintenance purposes only.

The schematic illustrates a complex electronic circuit featuring:

• 11 transistors (Q1-Q11)
• 22 diodes (D1-D22)
• 41 resistors (R1-R41)
• 9 capacitors (C1-C9)
• 9 transformers (T1-T9)

General component specifications are provided: resistors are 1/4W 5%, capacitors are MMFD (likely picoFarads), diodes are D664, and transformers are T-2052, unless otherwise indicated on the diagram.

Additional information includes a "Transistor & Diode Conversion Chart" listing DEC part numbers and their EIA equivalents (e.g., DEC1008 to MM1008, D662 to IN645). It also references an external Parts List (A-PL-6207) and includes revision details with personnel names (H. Porter, N. Perryman, Tom Hughes) and dates in February 1965.
