- dinosaurs mating — (humour) The activity said to occur when yet another big iron merger or buy-out occurs; reflects a perception by hackers that these signal another stage in the long, slow dying of the mainframe industry. Also described as "elephants mating": lots of noise and action at a high level, with an eventual outcome in the somewhat distant future. In its glory days of the 1960s, it was "IBM and the Seven Dwarves": Burroughs, Control Data, General Electric, Honeywell, NCR, RCA, and Univac. Early on, RCA sold out to Univac and GE also sold out, and it was "IBM and the BUNCH" (an acronym for Burroughs, Univac, NCR, Control Data, and Honeywell) for a while. Honeywell was bought out by Bull. Univac in turn merged with Sperry to form Sperry/Univac, which was later merged (although the employees of Sperry called it a hostile takeover) with Burroughs to form Unisys in 1986 (this was when the phrase "dinosaurs mating" was coined). In 1991 AT&T absorbed NCR, only to spit it out again in 1996. Unisys bought Convergent Technologies in 1988 and later others. More such earth-shaking unions of doomed giants seem inevitable.

- display standard — (hardware, standard) IBM and others have introduced a bewildering plethora of graphics and text display standards for IBM PCs. The standards are mostly implemented by plugging in a video display board (or "graphics adaptor") and connecting the appropriate monitor to it. Each new standard subsumes its predecessors. For example, an EGA board can also do CGA and MDA. With the PS/2, IBM introduced the VGA standard and built it into the main system board motherboard. VGA is also available as a plug-in board for PCs from third-party vendors. Also with the PS/2, IBM introduced the 8514 high-resolution graphics standard. An 8514 adaptor board plugs into the PS/2, providing a dual-monitor capability. Graphics software had to support the major IBM graphics standards and many non-IBM, proprietary standards for displays. Either software vendors provided display drivers or display vendors provided drivers for the software package. In either case, switching software or switching display systems was fraught with compatibility problems. More colours are available from third-party vendors for some display types. See also MDA, CGA, EGA, PGA, Hercules, MCGA, VGA, SVGA, 8514, VESA.
