The display technology was similar to the Tektronix [[4010]] terminal, using a [[direct-view storage CRT]] display (like an analog storage scope) to avoid the need for video RAM. It was all-in-one design with the display, keyboard, CPU and a 300 kByte [https://en.wikipedia.org/wiki/Quarter-inch_cartridge DC300 quarter-inch cartridge tape drive] in a single desktop case, and included a [[GPIB]] interface. A simple operating system and BASIC interpreter were included in ROM. | ||
The storage tube display allowed the screen to retain images drawn to it, eliminating the need for frame-buffer memory. This allowed the resolution to be as high as the hardware could handle, which was ostensibly 1024 by 1024 but limited by the physical layout of the screen to 1024 by 780. It also allowed the machine to dedicate all of its memory to the programs running on it, as opposed to partitioning off a section for the buffer. | The storage tube display allowed the screen to retain images drawn to it, eliminating the need for frame-buffer memory.
