G858 Teletype Connector

The G858 module functions as an interface between a PDP-15's Teletype receiver/transmitter (M706/M707) and an external Teletype. It utilizes a level converter to adjust signal levels between 0V/+30V and 0V/+3V, and includes an open-collector driver to provide drive current for the Teletype's reader. The document also lists the module's electrical specifications regarding input load, output drive capability, and power dissipation.
