68LC040
The Motorola 68040 ("''sixty-eight-oh-forty''") is a 32-bit microprocessor in the Motorola 68000 series, released in 1990. It is the successor to the 68030 and is followed by the 68060, skipping the 68050. In keeping with general Motorola naming, the 68040 is often referred to as simply the '040 (pronounced ''oh-four-oh'' or ''oh-forty''). The 68040 was the first 680x0 family member with an on-chip Floating-Point Unit (FPU). It thus included all of the functionality that previously required external chips, namely the FPU and Memory Management Unit (MMU), which was added in the 68030. It also had split instruction and data caches of 4 kilobytes each. It was fully pipelined, with six stages. Versions of the 68040 were created for specific market segments, including the 68LC040, which removed the FPU, and the 68EC040, which removed both the FPU and MMU. Motorola had intended the EC variant for embedded use, but embedded processors during the 68040's time did not need the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

32-bit Microprocessor
In computer architecture, 32-bit computing refers to computer systems with a processor, memory, and other major system components that operate on data in a maximum of 32-bit units. Compared to smaller bit widths, 32-bit computers can perform large calculations more efficiently and process more data per clock cycle. Typical 32-bit personal computers also have a 32-bit address bus, permitting up to 4 GiB of RAM to be accessed, far more than previous generations of system architecture allowed. 32-bit designs have been used since the earliest days of electronic computing, in experimental systems and then in large mainframe and minicomputer systems. The first hybrid 16/32-bit microprocessor, the Motorola 68000, was introduced in the late 1970s and used in systems such as the original Apple Macintosh. Fully 32-bit microprocessors such as the HP FOCUS, Motorola 68020 and Intel 80386 were launched in the early to mid 1980s and became dominant by the early 1990s. This generation of p ...

Macintosh LC
The Macintosh LC is a personal computer designed, manufactured, and sold by Apple Computer, Inc. from October 1990 to March 1992. Overview The first in the Macintosh LC family, the LC was introduced with the Macintosh Classic (a repackaging of the older Macintosh SE) and the Macintosh IIsi (a new entry-level machine for the Macintosh II series), and offered for half the price of the Macintosh II but significantly lesser in performance overall. The creation of the LC was prompted by Apple's desire to produce a product that could be sold to school boards for the same price as an Apple IIGS. It was designed for inexpensive manufacturing, with five major components that robots could assemble. The computer had a $2,400 list price; it and the new $600 12-inch color display were $3,500 less expensive than the Macintosh II. Not long after the Apple IIe Card was introduced for the LC, Apple quietly removed the IIGS from its price list, forcibly retiring it, as the company wanted ...

Apollo/Domain
Apollo/Domain is a series of workstations that were developed and produced by Apollo Computer from to 1989. The machines were built around the Motorola 68k series of processors, except for the DN10000, which has from one to four of Apollo's RISC processors, named Apollo PRISM, PRISM. Operating system The original operating system is Apollo's own product called Aegis, which was later renamed to Domain/OS. The Aegis and Domain/OS system offers advanced features for the time, for example an object oriented filesystem, network transparency, diskless booting, a graphical user interface, and, in Domain/OS, interoperability with Berkeley Software Distribution, BSD, UNIX System V, System V, and POSIX. Hardware An Apollo workstation resembles a modern PC, with a base unit, keyboard, mouse, and screen. Early models are housed in short (about 2 feet high) 19" rack cabinets to be set beside a desk or under a table. The DN300 and later DN330 were designed as integrated units with the sy ...

Apollo Computer
Apollo Computer Inc. was an American technology corporation headquartered and founded in Chelmsford, Massachusetts. It was founded in 1980 by William Poduska (a founder of Prime Computer) and others. Apollo Computer developed and produced Apollo/Domain workstations in the 1980s. Along with Symbolics and Sun Microsystems, Apollo was one of the first vendors of graphical workstations. Like other computer companies at the time, Apollo produced much of its own hardware and software. Apollo was acquired by Hewlett-Packard in 1989 for US$476 million (equivalent to $ million in ), and gradually closed down over the period of 1990–1997. The brand (as "HP Apollo") was resurrected in 2014 as part of HP's high-performance computing portfolio. History Apollo was started in 1980, two years before rival Sun Microsystems. In addition to Poduska, the founders included Dave Nelson (engineering), Mike Greata (engineering), Charlie Spector (COO), Bob Antonuccio (manufacturing), Gerry St ...
