4901
The Tektronix 4901 Interactive Graphic Unit (070-1059-00) is a plug-in for the 4002 terminal that interfaces with graphic input devices which output X and Y analog signals.
It interfaces with the 4002’s auxiliary I/O connector and is housed in the 4002 console space provided for auxiliary modules.
The 4901 generates a full-screen crosshair cursor controlled by external X/Y inputs. Upon command from the computer, the T4002 keyboard, or an external graphic device, it will digitize the crosshair cursor coordinates and send them to the computer through the I/O interface unit.
Tek also offered an analog joystick controller to plug into the 4901.
