Closeup of the pins of a pin grid array The pin grid array at the bottom of prototype Motorola 68020 microprocessor The pin grid array on the bottom of an AMD Phenom X4 9750 processor that uses the AMD AM2+ socket. A pin grid array (PGA) is a type of integrated circuit packaging. In a PGA, the package is square or rectangular, and the pins are ...
The FX-7000G incorporates an LCD Dot Matrix design via the display window. When set into character mode the calculator can display up to sixteen characters on each of its eight display lines. [4] This sixteen character by eight line display is screened on the 96 × 64 dot matrix. [4] The LCD is not capable of colour or grey scale display.
Gauge block, (also known as a gage block, Johansson gauge, slip gauge, or Jo block) a precision ground and lapped length measuring standard. It is used as a reference for the setting of measuring equipment used in machine shops , such as micrometers , sine bars , calipers , and dial indicators (when used in an inspection role ).
A 16×2-character dot-matrix display, where each character is made from a grid of 5×7 dots. A dot-matrix display is a low-cost electronic digital display device that displays information on machines such as clocks, watches, calculators, and many other devices requiring a simple alphanumeric (and/or graphic) display device of limited resolution.
At the other end of the size spectrum, machines with 2.4-to-3.0-metre-diameter (8 to 10 ft) plates are not uncommon, and systems with tables 9 m (30 ft) in diameter have been constructed. Referring to the second picture again, the lap is the large circular disk on the top of the machine. On top of the lap are two rings.
The individual gauge block is a metal or ceramic block that has been precision ground and lapped to a specific thickness. Gauge blocks come in sets of blocks with a range of standard lengths. In use, the blocks are stacked to make up a desired length (or height). Gauge blocks were invented in 1896 by Swedish machinist Carl Edvard Johansson. [1]
An IBM PC with a 5151 monitor. The IBM 5151 is a 12" transistor–transistor logic (TTL) monochrome monitor, shipped with the original IBM Personal Computer for use with the IBM Monochrome Display Adapter.
An IBM 2285 Display Copier could be attached to the 2250 to provide 8½ by 11 inch hard copy of the display contents under operator control. An IBM 2280 Film Recorder or IBM 2282 Film Recorder/Scanner could be attached to a 2840 control unit providing for output or input/output to photographic negative.
