The Tektronix 4052 is a graphics-capable desktop microcomputer produced by Tektronix in the late 1970s through the early 1980s. The display technology is similar to the Tektronix 4010 terminal, using a vector-driven direct-view storage CRT display (like an analog storage scope) to avoid the need for video RAM. The 4052 is an all-in-one design, with the display, keyboard, CPU and DC300 quarter-inch cartridge tape drive in a single desktop case, and includes a GPIB interface. A simple operating system and BASIC interpreter is included in ROM.

The storage tube display allows the screen to retain images drawn to it, eliminating the need for frame-buffer memory. This allows the resolution to be as high as the hardware can handle, which is 1024 by 1024 logically (i.e. DAC resolution) but limited by the physical layout of the screen to 1024 by 780. It also allows the machine to dedicate all of its memory to the programs running on it (as opposed to partitioning off a section for the buffer), an important consideration at the time when memory was expensive and scarce.

Released in 1978, the 4052 came with a full 32 kB of RAM for $9,795 (2016 value: $36,300) and could be expanded to 64 kB for another $1,995 (2016: $7,400).
