Write Driver G287

This document is a technical schematic for a "Write Driver G287" circuit, published by the Digital Equipment Corporation in 1967. The schematic details the arrangement of transistors (specifically DEC6534B and DEC3500 types), various diodes (including D662, D664, and D672), resistors, and a capacitor. The circuit is designed to operate between +10V and -15V power rails. Additionally, the document includes a conversion chart mapping the internal DEC part numbers to industry-standard (EIA) component numbers.
