Blit (computer terminal)
In computing, the Blit was a programmable bitmap graphics terminal designed by Rob Pike and Bart Locanthi Jr. of Bell Labs in 1982.
==History==
The Blit technology was commercialized by AT&T and Teletype. In 1984, the DMD (dot-mapped display) 5620 was released,〔(AT&T/Teletype 5620 Dot Mapped Display Terminal )〕 followed by models 630 MTG (multi-tasking graphics) in 1987 and 730 in 1989. The 5620 used a Western Electric 32000 processor (aka Bellmac 32) and had a 15" green phosphor display with 800×1024×1 resolution (66×88 characters in the initial text mode) interlaced at 30 Hz. The 630 and 730 had Motorola 68000 processors and a faster 1024×1024×1 monochrome display (most had orange displays, but some had white or green displays).
The folk etymology for the ''Blit'' name is that it stands for ''Bell Labs Intelligent Terminal'', and its creators have also joked that it actually stood for ''Bacon, Lettuce, and Interactive Tomato''. However, Rob Pike's paper on the Blit explains that it was named after the second syllable of ''bit blit'', a common name for the bit-block transfer operation that is fundamental to the terminal's graphics. Its original nickname was the ''jerq'', inspired by Three Rivers' PERQ graphic workstation.
