Macintosh LC 520
The Macintosh LC 500 series is a series of personal computers that were a part of Apple Computer's Macintosh LC family of Apple Macintosh, Macintosh computers, designed as a successor to the compact Macintosh family of computers for the mid-1990s mainstream education-market. The All-in-one PC, all-in-one desktop case is similar to the then recently introduced Macintosh Color Classic, but the LC 500 series is considerably larger and heavier due to its larger screen and a bulging midsection to house the larger electronics, including a 14" Cathode-ray tube, CRT display, CD-ROM drive, and stereo speakers. The LC 500 series included four main models, the 520, 550, 575, and 580, with the 520 and 550 both using different speeds of the Motorola 68030, and the 575 and 580 sharing the 33 MHz Motorola 68LC040 processor but differing on the rest of the hardware. All of these computers were also sold to the consumer market through department stores under the Macintosh Performa brand, with simi ...

Personal Computer
A personal computer (PC) is a multi-purpose microcomputer whose size, capabilities, and price make it feasible for individual use. Personal computers are intended to be operated directly by an end user, rather than by a computer expert or technician. Unlike large, costly minicomputers and mainframes, time-sharing by many people at the same time is not used with personal computers. Primarily in the late 1970s and 1980s, the term home computer was also used. Institutional or corporate computer owners in the 1960s had to write their own programs to do any useful work with the machines. While personal computer users may develop their own applications, usually these systems run commercial software, free-of-charge software ("freeware"), which is most often proprietary, or free and open-source software, which is provided in "ready-to-run", or binary, form. Software for personal computers is typically developed and distributed independently from the hardware or operating system ma ...

Macintosh Quadra 605
The Macintosh Quadra 605 (also sold as the Macintosh LC 475 and Macintosh Performa 475) is a personal computer designed, manufactured, and sold by Apple Computer from October 1993 to July 1996. The model names reflect a decision made at Apple in 1993 to follow an emerging industry trend of naming product families for their target customers Quadra for business, LC for education, and Performa for home. Accordingly, the Performa 475 and 476 was sold in department stores and electronics stores such as Circuit City, whereas the Quadra was purchased through an authorized Apple reseller. When introduced, the Quadra 605 was the least expensive new computer in Apple's lineup. (The Performa 410, introduced at the same time, at the same price of about $1,000 USD, which included a monitor, was based on the much older Macintosh LC II with a 16 MHz 68030 processor.) The Quadra 605 reuses the Macintosh LC III's pizza box form factor with minor modifications. The Quadra 605 was discon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mac OS 9
Mac OS 9 is the ninth major release of Apple Inc., Apple's classic Mac OS operating system which was succeeded by macOS, Mac OS X (renamed to OS X in 2011 and macOS in 2016) in 2001. Introduced on October 23, 1999, it was promoted by Apple as "The Best Internet Operating System Ever", highlighting Sherlock (software), Sherlock 2's Internet search capabilities, integration with Apple's free online services known as MobileMe#iTools, iTools and improved Open Transport networking. While Mac OS 9 lacks protected memory and full pre-emptive multitasking, lasting improvements include the introduction of an automated Apple Software Update, Software Update engine and support for multi-user, multiple users. Apple discontinued development of Mac OS 9 in late 2001, transitioning all future development to Mac OS X. The final updates to Mac OS 9 addressed compatibility issues with Mac OS X while running in the Classic Environment and compatibility with Carbon (API), Carbon applications. At the ...

Circuit City
Circuit City is an American consumer electronics retail company, which was founded in 1949 by Samuel Wurtzel as the Wards Company, operated stores across the United States, and pioneered the electronics superstore format in the 1970s. After multiple purchases and a successful run on the NYSE, it changed its name to Circuit City Stores Inc. The brand name was re-established by Ronny Shmoel in 2016 as part of his acquisition of the brand name and trademark rights sold by Systemax, which formerly operated the CircuitCity.com website from 2009 until 2012, when it was consolidated into the TigerDirect brand. History In early 1949, Wurtzel was on vacation in Richmond, Virginia when, while at a local barber shop, he was witness to the start of television in the South. Imagining the opportunities, in late 1949, he moved his family to Richmond and opened the first Wards Company retail store. Later, Abraham L. Hecht joined him as a partner in the business. By 1959, Wards Company o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

MacWEEK
''MacWEEK'' was a controlled-circulation weekly Apple Macintosh trade journal based in San Francisco founded by Michael Tchong, John Anderson, Glenn Patch, Dick Govatski, and Michael F. Billings. It featured a back-page rumor column penned by the pseudonymous Mac the Knife. Founded in 1987, it was acquired by Ziff-Davis in 1988. In 1998, as part of a strategy change, the print publication was relaunched as ''eMediaWeekly'', which caused a number of its existing sponsors to withhold their advertising. ''eMediaWeekly'' was published from August 24, 1998 to February 1, 1999. The online edition of MacWEEK continued for several years, originally under the editorial management of MacWEEK staff members and later under the management of former Macworld editors. It was later shuttered in favor of Mac Publishing's Macworld and MacCentral sites. Rumors about Apple and its products were often published in MacWEEK which essentially became the source of record.

Motorola 68882
The Motorola 68881 and Motorola 68882 are floating-point units (FPUs) used in some computer systems in conjunction with Motorola's 32-bit 68020 or 68030 microprocessors. These coprocessors are external chips, designed before floating point math became standard on CPUs. The Motorola 68881 was introduced in 1984. The 68882 is a higher performance version produced later. Overview The 68020 and 68030 CPUs were designed with the separate 68881 chip in mind. Their instruction sets reserved the "F-line" instructions – that is, all opcodes beginning with the hexadecimal digit "F" could either be forwarded to an external coprocessor or be used as "traps" which would throw an exception, handing control to the computer's operating system. If an FPU is not present in the system, the OS would then either call an FPU emulator to execute the instruction's equivalent using 68020 integer-based software code, return an error to the program, terminate the program, or crash and require a reboot ...
