History of Computing exam question

Hans asked: Fun question. Don't have time to really organize, but here's parts of my list: Napier's Bones digital solution for one class of computing problem Slide Rule (almost any) Analog computation, and portable computing power. Application of a fairly disjoint set of technologies to a very focussed solution that met a serious need in engineering Abacus (almost any) As with the slide rule, but now a discrete digital technology. Babbage's Engine ...or plans, if it couldn't be found or made a replica of. Large-scale compute power, digital technology with the greatest flexibility so far Bowditch's "American Practical Navigator" and a sextant Illustration of the market drive for computing power, and the tabular approach to meeting heavy-duty geometrical calculation problems. (Could just as well be the old Admiralty tables, I'm just biased in favor of Bowditch 'cause I'm American.) Zuse-1 (fill in the blank) Enigma machine, and Bomb (a matched pair) *serious* market drive -> compute power response for a single application Eniac (fill in the blank) IBM 360 (fill in the blank) PDP-11/xx Pick a good one, first minicomputer/lab computer. Brought compute power into a lot of lower-cost applications. Dec Rainbow typifies both MS-DOS and CP-M machines. somewhat breakthrough OS flexibility, (MS-DOS, CP/M, CCP/M, Venix, all of which were preexisting). Mac 128k GUI OS for the masses, origin of "friendly" computers (first computer to *smile* at me). VAX - any Illustration of successful extension of an existing architecture to more bits (twice as many) Alpha - any As VAX, but to 64 bits/RISC Cray 1 Vector supercomputer, electromechanical design breakthrough Newton PDA origin. Perq microprogramming, early workstation, heck Tony likes it so it must be good... F-14 flight computer integrated circuit microprocessor first application (?) NeXT Cube (original) OO system, sizeable leap in developer environment quality Sun Sparc-5 Desktop workstation, power/price/size breakthrough Sony Vaio or Mac Titanium Laptops get to practical size and retain serious power. DVD player (any) or CD player market driver for serious compute power cheap Sony PSX as above, including graphics Jet engine FADEC unit (any) compute power seriously ruggedized and making a pilot's life easier (livable). I'm sure I've left out a lot, apologies to all concerned. - Mark
