Usually, the standoff has a #6-32 UNC male thread on one end which screws into a threaded hole in the case or motherboard backplate and a #6-32 UNC female thread in the other end which accepts a screw to retain the motherboard. Less often, the standoff has a female thread in both ends and a second screw is used to attach it to the case.
In computer science, a thread of execution is the smallest sequence of programmed instructions that can be managed independently by a scheduler, which is typically a part of the operating system. [1] In many cases, a thread is a component of a process .
Big Mac was conceived as a 3M computer, with at least 1 megabyte of memory, a 1 megapixel display, and 1 million instructions per second. Similar to the later Macintosh Portrait Display , its 15 in (38 cm) display had a vertical orientation for word processing and was monochrome to save on costs. [ 5 ]
This is a "half-length" card, with a maximum length of 7 inches (18 cm). The maximum length for full-size NuBus cards is 12 inches (30 cm). NuBus (/ ˈ n (j) u ˌ b ʌ s /) is a 32-bit parallel computer bus, originally developed at MIT and standardized in 1987 as a part of the NuMachine workstation project. [1]
This is a list of all major types of Mac computers produced by Apple Inc. in order of introduction date. Macintosh Performa models were often physically identical to other models, in which case they are omitted in favor of the identical twin.
The Personal Computer Memory Card International Association (PCMCIA) was an industry association created in 1989 to promote a standard for memory cards in PCs, and worked closely with JEIDA, adopting their 68 pin connector design.
Mac 512K back panel. The Macintosh 512K is a personal computer that was designed, manufactured and sold by Apple Computer from September 1984 to April 1986. It is the first update to the original Macintosh 128K. It was virtually identical to the previous Macintosh, differing primarily in the amount of built-in random-access memory. The ...
The rule of thumb is a 286, 386SX, 68000 or low-end 68020 / 68030 (e.g. Atari Falcon, Mac LC) system (using a 16 bit wide data bus) would require two 30-pin SIMMs for a memory bank. On 386DX , 486 , and full-spec 68020 through 68060 (e.g. Atari TT, Amiga 4000, Mac II) systems (32 bit data bus), either four 30-pin SIMMs or one 72-pin SIMM are ...
