instead only provided the basic mechanisms on top of which several different user interface styles were later implemented. At least three major user interface look & feel styles were widely used on X - MIT's own Athena style, Sun and AT&T's OpenLook, and OSF's Motif (supported primarily by HP and IBM). Other less significant styles included Digital's DECwindows, Silicon Graphics' 4Sight and several public domain styles. None of the styles interacted particularly well with the others, and as a result X was plagued by inconsistencies between applications.The Atari STKnown primarily as a maker of games machines, the Atari ST was Atari's first major foray into the world of personal computing. Like the Macintosh and Amiga, the Atari ST was based on the Motorola 68000 processor. It offered medium resolution color graphics and high quality stereo sound, and its GEM operating system featured a graphical user interface.Unfortunately, for mainstream business uses the ST couldn't compete with the PC and Macintosh, and for graphics and games it couldn't compete with the Amiga. As a result, the ST struggled to find its place in the market. Eventually it managed to carve out a niche in the music and audio editing market, where many music professionals used it as an advanced sound mixing and sound effects machine.MIPS - The First Commercial RISCThe MIPS R2000, introduced in June 1986, was [arguably] the first commercial RISC processor. It was a descendant of the Stanford MIPS project led by John Hennessy, one of the three pioneering RISC research projects of the early 1980's. In stark contrast to the complicated CISC architectures of the 1980's, the MIPS architecture only had about 50 instructions and was a load store architecture with just a single addressing mode. Instead of achieving high performance through complexity, the MIPS design had 64 registers (32 int + 32 fp) and used an efficient pipelined design to achieve almost one instruction per cy...
