A microcomputer is a small, relatively inexpensive computer having a central processing unit (CPU) made out of a microprocessor. The computer also includes memory and input/output (I/O) circuitry together mounted on a printed circuit board (PCB). Microcomputers became popular in the 1970s and 1980s with the advent of increasingly powerful microprocessors. The predecessors to these computers, mainframes and minicomputers, were comparatively much larger and more expensive. Many microcomputers are also personal computers. An early use of the term "personal computer" in 1962 predates microprocessor-based designs. (See "Personal Computer: Computers at Companies" reference below). A "microcomputer" used as an embedded control system may have no human-readable input and output devices. "Personal computer" may be used generically or may denote an IBM PC compatible machine.
In computer engineering, a hardware description language (HDL) is a specialized computer language used to describe the structure and behavior of electronic circuits, most commonly to design ASICs and program FPGAs.
The Hercules Graphics Card (HGC) is a computer graphics controller formerly made by Hercules Computer Technology, Inc. that combines IBM's text-only MDA display standard with a bitmapped graphics mode, also offering a parallel printer port. This allows the HGC to offer both high-quality text and graphics from a single card.
Reconfigurable computing is a computer architecture combining some of the flexibility of software with the high performance of hardware by processing with flexible hardware platforms like field-programmable gate arrays (FPGAs). The principal difference when compared to using ordinary microprocessors is the ability to add custom computational blocks using FPGAs. On the other hand, the main difference from custom hardware, i.e. application-specific integrated circuits (ASICs) is the possibility to adapt the hardware during runtime by "loading" a new circuit on the reconfigurable fabric, thus providing new computational blocks without the need to manufacture and add new chips to the existing system.
The IMSAI 8080 is an early microcomputer released in late 1975, based on the Intel 8080 and S-100 bus. It is a clone of its main competitor, the earlier MITS Altair 8800. The IMSAI is largely regarded as the first "clone" microcomputer. The IMSAI machine runs a highly modified version of the CP/M operating system called IMDOS. It was developed, manufactured and sold by IMS Associates, Inc.. In total, between 17,000 and 20,000 units were produced from 1975 to 1978.
The Commodore 65 is a prototype computer created at Commodore Business Machines in 1990–1991. It is an improved version of the Commodore 64, and it was meant to be backwards-compatible with the older computer, while still providing a number of advanced features close to those of the Amiga.
The Commodore 64 Games System is the cartridge-based home video game console version of the popular Commodore 64 home computer. It was released in December 1990 by Commodore into a booming console market dominated by Nintendo and Sega. It was only released in Europe and was a considerable commercial failure. The C64GS came bundled with a cartridge containing four games: Fiendish Freddy's Big Top O'Fun, International Soccer, Flimbo's Quest, and Klax.
Hardware acceleration is the use of computer hardware designed to perform specific functions more efficiently when compared to software running on a general-purpose central processing unit (CPU). Any transformation of data that can be calculated in software running on a generic CPU can also be calculated in custom-made hardware, or in some mix of both.
Retrogaming, also known as classic gaming and old school gaming, is the playing and collection of obsolete personal computers, consoles, and video games. Usually, retrogaming is based upon systems that are outmoded or discontinued, although ported retrogaming allows games to be played on modern hardware via ports or compilations. It is typically for nostalgia, preservation, or authenticity. A new game could be retro styled, such as an RPG with turn-based combat and pixel art in isometric camera perspective.
The Replica 1 is a clone of the historic Apple I of 1976. It was designed by Vince Briel in 2003. It was the first Apple 1 clone to take advantage of more modern components, enabling the clone to be produced with cheaper and more widely available components while retaining the functionality of the original.
The Amiga is a family of home computers that were designed and sold by the Amiga Corporation from 1985 to 1994.
This is a glossary of terms used in the field of Reconfigurable computing and reconfigurable computing systems, as opposed to the traditional Von Neumann architecture.
Semulation is a computer science-related portmanteau of simulation and emulation, signifying the process of controlling an emulation through a simulator.
Aldec, Inc. is a privately owned electronic design automation company based in Henderson, Nevada that provides software and hardware used in creation and verification of digital designs targeting FPGA and ASIC technologies.
In computing, an emulator is hardware or software that enables one computer system to behave like another computer system. An emulator typically enables the host system to run software or use peripheral devices designed for the guest system. Emulation refers to the ability of a computer program in an electronic device to emulate another program or device.
The MRB Z 1013 was an East German single-board computer produced by VEB Robotron Riesa, which was primarily intended for private use and educational institutions. It was powered by a U880 processor and sold together with a membrane keyboard. Initially, the kit was equipped with 16 kilobytes of DRAM, which was later replaced by a 64 KB version.
1541 Ultimate is a peripheral, primarily an emulated floppy disk and cartridge emulator based on the FPGA Xilinx XC3S250E, for the Commodore 64 home computer. It became available in 2008.
David Murray, commonly known as The 8-Bit Guy, is an American retrocomputing enthusiast and video game developer who runs a YouTube channel under the same name.
A vintage computer is an older computer system that is largely regarded as obsolete.
