The Tektronix 4012 is a text-and-graphics computer terminal that added lower case characters to the base 4010 model. The Tektronix 4012 was implemented using plug-in boards that could be added to the base-model 4010. The Tektronix 4012 came pre-installed with the printer adaptor for the 4610 Hard Copy Unit.[1]

How it works
The Tektronix 4012 uses a direct-view bistable storage tube for display. Images drawn to the screen remain visible until deliberately erased, eliminating the need for a refresh buffer or dedicated memory to store the image.[1]
Where it fits in the process flow
The terminal connects to the host through an adaptor, and can be paired with peripherals like hard copy units and plotters for output.[1]
Applications
Software such as PLOT10, a set of graphics routines in FORTRAN, was provided to generate graphical output on the terminal.[1]
