Mouse Systems
Mouse Systems Corporation (MSC), formerly Rodent Associates, was founded in 1982 by Steve Kirsch. The company was responsible for bringing the mouse to the IBM PC for the first time. History Mouse Systems' optical mouse, wired to a Sun workstation and an Atari 400 running ''Missile Command'', attracted many observers at the October, 1982 Mini/Micro '82 conference in Anaheim, attended by over people—and won a "best new product" award. In 1982, MSC acquired rights to PCPaint from Microtex Industries, the first mouse-driven image manipulation program for the IBM PC, written in assembly language by Doug Wolfgram. Mouse Systems wanted the software re-developed to look more like Apple's MacPaint so Wolfgram brought in co-developer John Bridges and together they re-wrote the program in C with an updated user interface. Millions of copies were shipped, primarily bundled with all their mice until the early 1990s. KYE Systems, producer of the Genius brand of mice, acquired Mouse Sys ...

Fremont, California
Fremont is a city in Alameda County, California, United States. Located in the East Bay region of the San Francisco Bay Area, Bay Area, Fremont has a population of 230,504 as of 2020, making it the fourth List of cities and towns in the San Francisco Bay Area, most populous city in the Bay Area, behind San Jose, California, San Jose, San Francisco, and Oakland, California, Oakland. It is the closest East Bay city to the high-tech Silicon Valley network of businesses, and has a strong tech industry presence. The city's origins lie in the community that arose around Mission San José (California), Mission San José, founded in 1797 by the Spanish under Padre Fermín Lasuén. Fremont was incorporated on January 23, 1956, when the former towns of Mission San José (California), Mission San José, Centerville, Niles, Irvington, and Warm Springs unified into one city. Fremont is named after John C. Frémont, a general who helped lead the American Conquest of California from Mexico and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RS-232
In telecommunications, RS-232 or Recommended Standard 232 is a standard originally introduced in 1960 for serial communication transmission of data. It formally defines signals connecting between a ''DTE'' (''data terminal equipment'') such as a computer terminal, and a ''DCE'' (''data circuit-terminating equipment'' or ''data communication equipment''), such as a modem. The standard defines the electrical characteristics and timing of signals, the meaning of signals, and the physical size and pinout of connectors. The current version of the standard is ''TIA-232-F Interface Between Data Terminal Equipment and Data Circuit-Terminating Equipment Employing Serial Binary Data Interchange'', issued in 1997. The RS-232 standard had been commonly used in computer serial ports and is still widely used in industrial communication devices. A serial port complying with the RS-232 standard was once a standard feature of many types of computers. Personal computers used them for connection ...

1990 Mergers And Acquisitions
Year 199 ( CXCIX) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was sometimes known as year 952 ''Ab urbe condita''. The denomination 199 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

I/O Address
Memory-mapped I/O (MMIO) and port-mapped I/O (PMIO) are two complementary methods of performing input/output (I/O) between the central processing unit (CPU) and peripheral devices in a computer. An alternative approach is using dedicated I/O processors, commonly known as channels on mainframe computers, which execute their own instructions. Memory-mapped I/O uses the same address space to address both main memory and I/O devices. The memory and registers of the I/O devices are mapped to (associated with) address values. So a memory address may refer to either a portion of physical RAM, or instead to memory and registers of the I/O device. Thus, the CPU instructions used to access the memory can also be used for accessing devices. Each I/O device monitors the CPU's address bus and responds to any CPU access of an address assigned to that device, connecting the data bus to the desired device's hardware register. To accommodate the I/O devices, some areas of the address bus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ISA Card
Industry Standard Architecture (ISA) is the 16-bit internal bus of IBM PC/AT and similar computers based on the Intel 80286 and its immediate successors during the 1980s. The bus was (largely) backward compatible with the 8-bit bus of the 8088-based IBM PC, including the IBM PC/XT as well as IBM PC compatibles. Originally referred to as the PC bus (8-bit) or AT bus (16-bit), it was also termed ''I/O Channel'' by IBM. The ISA term was coined as a retronym by competing PC-clone manufacturers in the late 1980s or early 1990s as a reaction to IBM attempts to replace the AT-bus with its new and incompatible Micro Channel architecture. The 16-bit ISA bus was also used with 32-bit processors for several years. An attempt to extend it to 32 bits, called Extended Industry Standard Architecture (EISA), was not very successful, however. Later buses such as VESA Local Bus and PCI were used instead, often along with ISA slots on the same mainboard. Derivatives of the AT bus structure ...

COM Port
COM (communication port) is the original, yet still common, name of the serial port interface on PC-compatible computers. It can refer not only to physical ports, but also to emulated ports, such as ports created by Bluetooth or USB adapters. History The name for the COM port started with the original IBM PC. IBM had called the four well-defined communication RS-232 ports the "COM" ports, starting from COM1 through COM4. In BASICA and PC DOS you can open these ports as "COM1:" through "COM4:", and all PC compatibles using MSDOS used the same denotation. Most PC-compatible computers in the 1980s and 1990s had one or two COM ports. By 2007, most computers shipped with only one or no physical COM ports. Today few consumer-grade PC-compatible computers include COM ports, though some of them do still include a COM header on the motherboard. After the RS-232 COM port was removed from most consumer-grade computers, an external USB-to-UART serial adapter cable was used to compen ...

8250 UART
The 8250 UART (universal asynchronous receiver/transmitter) is an integrated circuit designed for implementing the interface for serial communications. The part was originally manufactured by the National Semiconductor Corporation. It was commonly used in PCs and related equipment such as printers or modems. The 8250 included an on-chip programmable bit rate generator, allowing use for both common and special-purpose bit rates which could be accurately derived from an arbitrary crystal oscillator reference frequency. The chip designations carry suffix letters for later versions of the same chip series. For example, the original 8250 was soon followed by the 8250A and 8250B versions that corrected some bugs. In particular, the original 8250 could repeat transmission of a character if the CTS line was asserted asynchronously during the first transmission attempt. Due to the high demand, other manufacturers soon began offering compatible chips. Western Digital offered WD8250 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bus Mouse
A bus mouse is a variety of PC computer mouse which is attached to the computer using a specialized interface (originally, the Microsoft InPort interface developed for Microsoft's original mouse product). In the late 1980s, mice were not integrated with IBM-compatible personal computers, and the specialized bus interface (implemented via an ISA add-in card) was one of two popular ways to connect a mouse; serial interfaces were the other method. In addition to Microsoft, Logitech also made bus mouse interface cards. When the IBM PS/2 was introduced, it included a motherboard mouse interface which was integrated with the keyboard controller (still called the PS/2 mouse interface long after the PS/2 brand was withdrawn); this fairly quickly drove the bus mouse design out of the marketplace. The bus mouse lived on in the NEC PC-98 family of personal computers in Japan. See also * BIOS interrupt call * PS/2 port The PS/2 port is a 6-pin mini-DIN connector used for co ...
