- The Tektronix 4050 is a series of three computer graphics microcomputers produced by Tektronix in the late 1970s through the early 1980s. The display technology is similar to the Tektronix 4010 terminal, using a storage tube display to avoid the need for video RAM. They are all-in-one designs with the display, keyboard, CPU and DC300 tape drive in a single desktop case. They also include a GPIB parallel bus interface for controlling lab and test equipment as well as connecting to external peripherals. A simple operating system and BASIC interpreter are included in ROM. A key concept of the systems is the use of a storage tube for the display. This allows the screen to retain images drawn to it, eliminating the need for a framebuffer, computer memory devoted to the display. Most systems of the era had limited resolution due to the expense of the buffer needed to hold higher resolution images, but this is eliminated in the 4050s and allows the resolution to be as high as the hardware can handle, which was ostensibly 1024 by 1024 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. (en)
