Pea \Pea\, n.; pl. {Peas}or {Pease}. [OE. pese, fr. AS. pisa, or OF. peis, F. pois; both fr. L. pisum; cf. Gr. [?], [?]. The final s was misunderstood in English as a plural ending. Cf. {Pease}.] 1. (Bot.) A plant, and its fruit, of the genus {Pisum}, of many varieties, much cultivated for food. It has a papilionaceous flower, and the pericarp is a legume, popularly called a pod. Note: When a definite number, more than one, is spoken of, the plural form peas is used; as, the pod contained nine peas; but, in a collective sense, the form pease is preferred; as, a bushel of pease; they had pease at dinner. This distinction is not always preserved, the form peas being used in both senses. 2. A name given, especially in the Southern States, to the seed of several leguminous plants (species of {Dolichos}, {Cicer}, {Abrus}, etc.) esp. those having a scar (hilum) of a different color from the rest of the seed. Note: The name pea is given to many leguminous plants more or less closely related to the common pea. See the Phrases, below. {Beach pea} (Bot.), a seashore plant, {Lathyrus maritimus}. {Black-eyed pea}, a West Indian name for {Dolichos sph[91]rospermus} and its seed. {Butterfly pea}, the American plant {Clitoria Mariana}, having showy blossoms. {Chick pea}. See {Chick-pea}. {Egyptian pea}. Same as {Chick-pea}. {Everlasting pea}. See under {Everlasting}. {Glory pea}. See under {Glory}, n. {Hoary pea}, any plant of the genus {Tephrosia}; goat's rue. {Issue pea}, {Orris pea}. (Med.) See under {Issue}, and {Orris}. {Milk pea}. (Bot.) See under {Milk}. {Pea berry}, a kind of a coffee bean or grain which grows single, and is round or pea-shaped; often used adjectively; as, pea-berry coffee. {Pea bug}. (Zo[94]l.) Same as {Pea weevil}. {Pea coal}, a size of coal smaller than nut coal. {Pea crab} (Zo[94]l.), any small crab of the genus {Pinnotheres}, living as a commensal in bivalves; esp., the European species ({P. pisum}) which lives in the common mussel and the cockle. {Pea dove} (Zo[94]l.), the American ground dove. {Pea-flower tribe} (Bot.), a suborder ({Papilionace[91]}) of leguminous plants having blossoms essentially like that of the pea. --G. Bentham. {Pea maggot} (Zo[94]l.), the larva of a European moth ({Tortrix pisi}), which is very destructive to peas. {Pea ore} (Min.), argillaceous oxide of iron, occurring in round grains of a size of a pea; pisolitic ore. {Pea starch}, the starch or flour of the common pea, which is sometimes used in adulterating wheat flour, pepper, etc. {Pea tree} (Bot.), the name of several leguminous shrubs of the genus {Caragana}, natives of Siberia and China. {Pea vine}. (Bot.) (a) Any plant which bears peas. (b) A kind of vetch or tare, common in the United States ({Lathyrus Americana}, and other similar species). {Pea weevil} (Zo[94]l.), a small weevil ({Bruchus pisi}) which destroys peas by eating out the interior. {Pigeon pea}.

PDP-10 n. [Programmed Data Processor model 10] The machine that made timesharing real. It looms large in hacker folklore because of its adoption in the mid-1970s by many university computing facilities and research labs, including the MIT AI Lab, Stanford, and CMU. Some aspects of the instruction set (most notably the bit-field instructions) are still considered unsurpassed. The 10 was eventually eclipsed by the VAX machines (descendants of the PDP-11) when {DEC} recognized that the 10 and VAX product lines were competing with each other and decided to concentrate its software development effort on the more profitable VAX. The machine was finally dropped from DEC's line in 1983, following the failure of the Jupiter Project at DEC to build a viable new model. (Some attempts by other companies to market clones came to nothing; see {Foonly} and {Mars}.) This event spelled the doom of {{ITS}} and the technical cultures that had spawned the original Jargon File, but by mid-1991 it had become something of a badge of honorable old-timerhood among hackers to have cut one's teeth on a PDP-10. See {{TOPS-10}}, {{ITS}}, {BLT}, {DDT}, {DPB}, {EXCH}, {HAKMEM}, {LDB}, {pop}, {push}. See also `http://www.inwap.com/pdp10/'. | |

PDP-20 n. The most famous computer that never was. {PDP-10} computers running the {{TOPS-10}} operating system were labeled `DECsystem-10' as a way of differentiating them from the PDP-11. Later on, those systems running {TOPS-20} were labeled `DECSYSTEM-20' (the block capitals being the result of a lawsuit brought against DEC by Singer, which once made a computer called `system-10'), but contrary to popular lore there was never a `PDP-20'; the only difference between a 10 and a 20 was the operating system and the color of the paint. Most (but not all) machines sold to run TOPS-10 were painted `Basil Blue', whereas most TOPS-20 machines were painted `Chinese Red' (often mistakenly called orange). | |

PDP-11 Programmed Data Processor model 11. A series of {minicomputer}s based on an {instruction set} designed by C. Gordon Bell at {DEC} in the early 1970s (late 60s?). The PDP-11 family, which came after, but was not derived from, the {PDP-10}, was the most successful computer of its time until it was itself succeeded by the {VAX}. Models included the 11/23 and 11/24 (based on the F11 chipset); 11/44, 11/04, 11/34, 11/05, 11/10, 11/15, 11/20, 11/35, 11/40, 11/45, 11/70, 11/60 ({MSI} and {SSI}); LSI-11/2 and LSI-11 (LSI-11 chipset). In addition there were the 11/8x (J11 chipset) and SBC-11/21 (T11 chip) and then there was compatibility mode in the early {VAX} processors. The {B} and {C} languages were both used initially to implement {Unix} on the PDP-11. The {microprocessor} design tradition owes a heavy debt to the PDP-11 {instruction set}. See also {SEX}.

PDP-6 designed around 1960 with more or less exactly the same hardware architecture as the {PDP-10}. It already had multi-user {time sharing} and {batch processing} and multi-level priority {interrupts} (1996-12-21) | |

PDP-7 memory cycle time of 1.75 microseconds and add time of 4 microseconds. I/O included a keyboard, printer, {paper-tape} and dual transport DECtape drives (type 555). DEC provided an "advanced" {Fortran II} {compiler}, a Symbolic {Assembler}, Editor, {DDT} Debugging System, Maintenance routines and a library of arithmetic, utility and programming aids developed on the program-compatible {PDP-4}. [DEC sales brochure]. The PDP-7 was considered reliable enough (when properly programmed) to be used for control of nuclear reactors and such. Around 1970 {Ken Thompson} built the {operating system} that became {Unix} on a scavenged {PDP-7} so he could play a descendant of the {SPACEWAR} game. (1995-03-10) | |
