Smaky
The Smaky is a line of mostly 8-bit personal computers and accompanying operating system developed by Professor Jean-Daniel Nicoud and others at the École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland beginning in 1974. The computers were used at École Polytechnique Fédérale de Lausanne and in Swiss schools. The names derives from SMArt KeYboard, reflecting the form factor that contained a compact motherboard which fit within the same housing as the keyboard. The first three models, Smaky 1, Smaky 2, and Smaky 4, were based on the Intel 8080 microprocessor (Smaky 3 was a prototype that was never completed). In 1978, the Smaky switched to using the 8-bit Zilog Z80 processor. A portable Smaky was made during this period, which resembled Osborne portable computers. In 1981, the platform again changed to the 32-bit Motorola 68000 processor. A new operating system was written, called Psos, which was developed specifically for the Smaky, and used on all subsequent mod ...

Jean-Daniel Nicoud
Jean-Daniel Nicoud (born 31 August 1938), is a Swiss computer scientist, noted for inventing of a computer mouse with an optical encoder and the CALM (Common Assembly Language for microprocessors). He obtained a degree in physics at the École Polytechnique Fédérale de Lausanne (EPFL) in 1963. Around 1965, he became interested in logical systems. He obtained his PhD at the EPFL in 1970 and became a professor in 1973. His laboratory, LAMI (''LAboratoire de Micro-Informatique''), developed the Smaky computer, in addition to the optical computer mouse, an update of the traditional kinetic mouse invented by Douglas Engelbart. The Khepera mobile robot The Khepera is a small (5.5 cm) differential wheeled mobile robot that was developed at the LAMI laboratory of Professor Jean-Daniel Nicoud at EPFL (Lausanne, Switzerland) in the mid 1990s.

André Guignard
André Guignard is a Swiss engineer initially educated as a watchmaker. He is the creator of the mechanic of the Khepera, the S-bot and several other mobile robots. Working at the LAMI of the EPFL with Professor Jean-Daniel Nicoud, he designed and realised in 1977 the first modern computer mouse, that started the successful Logitech diversification. Born in 1942, he was enrolled at the EPFL in 1976 and made many research projects successful due to an exceptional mastering of how to conceive and build micromechanical systems. His interaction with students was always greatly appreciated. He retired in March 2007, but still helps part time with EPFL research projects. The Swiss Mouse Prototypes of an improved Engelbart mouse with an optical encoder were built at LAMI-EPFL in 1972, see EPFL mouse story but there was no need for a mouse when graphic screens were not available. The LAMI-EPFL developed several microprocessor driven graphic screens since 1974 and André Guignard de ...

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 ...

Computer Mouse
A computer mouse (plural mice, sometimes mouses) is a hand-held pointing device that detects two-dimensional motion relative to a surface. This motion is typically translated into the motion of a pointer on a display, which allows a smooth control of the graphical user interface of a computer. The first public demonstration of a mouse controlling a computer system was in 1968. Mice originally used two separate wheels to track movement across a surface: one in the X-dimension and one in the Y. Later, the standard design shifted to utilize a ball rolling on a surface to detect motion. Most modern mice use optical sensors that have no moving parts. Though originally all mice were connected to a computer by a cable, many modern mice are cordless, relying on short-range radio communication with the connected system. In addition to moving a cursor, computer mice have one or more buttons to allow operations such as the selection of a menu item on a display. Mice often also feature ...

UAE (emulator)
UAE is a computer emulator which emulates the hardware of Commodore International's Amiga range of computers. Released under the GNU General Public License, UAE is free software. History Bernd Schmidt conceived of an emulator that can run Amiga software when he found that such a task was widely believed to be impossible. Schmidt had written previous programs for Amiga, and was further motivated by the desire to not lose games, demos, and sound modules to switching operating systems. UAE was released in 1995 and was originally called the ''Unusable Amiga Emulator'', due to its inability to boot. In its early stages, it was known as ''Unix Amiga Emulator'' and later with other names as well. Since none of the popular expansions fit any more, the abbreviation no longer stands for anything, and the software is simply known as UAE — this occasionally gets backronymed as Universal Amiga Emulator, Ultimate Amiga Emulator or Ubiquitous Amiga Emulator. Features UAE is almost a fu ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Microsoft Windows
Windows is a group of several proprietary graphical operating system families developed and marketed by Microsoft. Each family caters to a certain sector of the computing industry. For example, Windows NT for consumers, Windows Server for servers, and Windows IoT for embedded systems. Defunct Windows families include Windows 9x, Windows Mobile, and Windows Phone. The first version of Windows was released on November 20, 1985, as a graphical operating system shell for MS-DOS in response to the growing interest in graphical user interfaces (GUIs). Windows is the most popular desktop operating system in the world, with 75% market share , according to StatCounter. However, Windows is not the most used operating system when including both mobile and desktop OSes, due to Android's massive growth. , the most recent version of Windows is Windows 11 for consumer PCs and tablets, Windows 11 Enterprise for corporations, and Windows Server 2022 for servers.

Motorola 68040
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 powe ...

Motorola 68000
The Motorola 68000 (sometimes shortened to Motorola 68k or m68k and usually pronounced "sixty-eight-thousand") is a 16/32-bit complex instruction set computer (CISC) microprocessor, introduced in 1979 by Motorola Semiconductor Products Sector. The design implements a 32-bit instruction set, with 32-bit registers and a 16-bit internal data bus. The address bus is 24 bits and does not use memory segmentation, which made it easier to program for. Internally, it uses a 16-bit data arithmetic logic unit (ALU) and two more 16-bit ALUs used mostly for addresses, and has a 16-bit external data bus. For this reason, Motorola termed it a 16/32-bit processor. As one of the first widely available processors with a 32-bit instruction set, and running at relatively high speeds for the era, the 68k was a popular design through the 1980s. It was widely used in a new generation of personal computers with graphical user interfaces, including the Macintosh 128K, Amiga, Atari ST, and X68000. Th ...

Osborne 1
The Osborne 1 is the first commercially successful portable computer, released on April 3, 1981 by Osborne Computer Corporation. It weighs , cost US$1,795, and runs the CP/M 2.2 operating system. It is powered from a wall socket, as it has no on-board battery, but it is still classed as a portable device since it can be hand-carried when the keyboard is closed. The computer shipped with a large bundle of software that was almost equivalent in value to the machine itself, a practice adopted by other CP/M computer vendors. Competitors quickly appeared, such as the Kaypro II. History The Osborne 1 was developed by Adam Osborne and designed by Lee Felsenstein, first announced in early 1981. Osborne, an author of computer books decided that he wanted to break the price of computers. The computer's design was based largely on the Xerox NoteTaker, a prototype developed at Xerox PARC in 1976 by Alan Kay. It was designed to be portable, with a rugged ABS plastic case and a handle.

Zilog Z80
The Z80 is an 8-bit microprocessor introduced by Zilog as the startup company's first product. The Z80 was conceived by Federico Faggin in late 1974 and developed by him and his 11 employees starting in early 1975. The first working samples were delivered in March 1976, and it was officially introduced on the market in July 1976. With the revenue from the Z80, the company built its own chip factories and grew to over a thousand employees over the following two years. The Zilog Z80 is a software-compatible extension and enhancement of the Intel 8080 and, like it, was mainly aimed at embedded systems. Although used in that role, the Z80 also became one of the most widely used CPUs in desktop computers and home computers from the 1970s to the mid-1980s. It was also common in military applications, musical equipment such as synthesizers (like the Roland Jupiter-8), and coin-operated arcade games of the late 1970s and early 1980s, including '' Pac-Man''.
