Advertisement for Mathatronics Mathatron II Multi-User Calculator System

The Mathatron II "CPU" provided connections for up to 16 Mathatronics Mathwriter keyboard units (which could connect via hard-wired or dial-up telephone lines), or ASR-33 Teletype terminals. The CPU would timeshare the remote terminals to make it appear as if each terminal was its own sophisticated programmable calculator. Top photo shows the Mathatron PKB remote keyboard. Middle photo is the Mathatron II "CPU", and the bottom photo is the Model 33ASR Teletype that can be connected to the system as an interactive terminal.
