Compositing window managerA compositing manager, or compositor, is software that provides applications with an off-screen buffer for each window. The compositing manager composites the window buffers into an image representing the screen and writes the result into the display memory. A compositing window manager is a window manager that is also a compositing manager. Compositing managers may perform additional processing on buffered windows, applying 2D and 3D animated effects such as blending, fading, , rotation, duplication, bending and contortion, shuffling, blurring, redirecting applications, and translating windows into one of a number of displays and virtual desktops.
Amiga CD32The Amiga CD32 (stylized as Amiga CD32, code-named "Spellbound") is a 32-bit home video game console developed by Commodore and released in Europe, Australia, Canada, and Brazil. It was first announced at the Science Museum in London on July 16, 1993, and was released in September of the same year. The CD32 is part of a family of Amiga computers and other hardware. It uses CD-ROM as its storage medium. It was based on Commodore's Advanced Graphics Architecture chipset, and is of similar specification to the Amiga 1200 personal computer.
Amiga 600The Amiga 600, also known as the A600, is a home computer introduced in March 1992. It is the final Amiga model based on the Motorola 68000 and the 1990 Amiga Enhanced Chip Set. A redesign of the Amiga 500 Plus, it adds the option of an internal hard disk drive and a PCMCIA port. Lacking a numeric keypad, the A600 is only slightly larger than an IBM PC keyboard, weighing approximately 6 pounds. It shipped with AmigaOS 2.0, which was considered more user-friendly than earlier versions of the operating system.
Apple IIGSThe Apple IIGS (styled as II), the fifth and most powerful of the Apple II family, is a 16-bit personal computer produced by Apple Computer. While featuring the Macintosh look and feel, and resolution and color similar to the Amiga and Atari ST, it remains compatible with earlier Apple II models. The "GS" in the name stands for "Graphics and Sound", referring to its enhanced multimedia hardware, especially its state-of-the-art audio.
BlitterA blitter is a circuit, sometimes as a coprocessor or a logic block on a microprocessor, dedicated to the rapid movement and modification of data within a computer's memory. A blitter can copy large quantities of data from one memory area to another relatively quickly, and in parallel with the CPU, while freeing up the CPU's more complex capabilities for other operations. A typical use for a blitter is the movement of a bitmap, such as windows and fonts in a graphical user interface or images and backgrounds in a 2D video game.
Sound BlasterSound Blaster is a family of sound cards and audio peripherals designed by Singaporean technology company Creative Technology (known in the US as Creative Labs). The first Sound Blaster card was introduced in 1989, and since then, the Sound Blaster brand has become synonymous with high-quality computer audio.
Motorola 68010The Motorola MC68010 processor is a 16/32-bit microprocessor from Motorola, released in 1982 as the successor to the Motorola 68000. It fixes several small flaws in the 68000, and adds a few features. The 68010 is pin-compatible with the 68000, but is not 100% software compatible. Some of the differences were: The MOVE from SR instruction is now privileged (it may only be executed in supervisor mode). This means that the 68010 meets Popek and Goldberg virtualization requirements.
Amiga models and variantsThis is a list of models and clones of Amiga computers. The first Amiga computer was the "Lorraine" developed using the Sage IV system. It consisted of a stack of breadboarded circuit boards. These models are not hardware compatible with the 68k Amigas. These chipsets were planned but never fabricated. Some computers were released by other companies which were AmigaOS compatible. DraCo: Released by MacroSystem in 1994. This was a high end machine which ran AmigaOS 3.1, but did not include the Amiga chipset, instead using a graphics card.
Real-time clockA real-time clock (RTC) is an electronic device (most often in the form of an integrated circuit) that measures the passage of time. Although the term often refers to the devices in personal computers, servers and embedded systems, RTCs are present in almost any electronic device which needs to keep accurate time of day. The term real-time clock is used to avoid confusion with ordinary hardware clocks which are only signals that govern digital electronics, and do not count time in human units.
Bit blitBit blit (also written BITBLT, BIT BLT, BitBLT, Bit BLT, Bit Blt etc., which stands for bit block transfer) is a data operation commonly used in computer graphics in which several bitmaps are combined into one using a boolean function. The operation involves at least two bitmaps: a "source" (or "foreground") and a "destination" (or "background"), and possibly a third that is often called the "mask". The result may be written to a fourth bitmap, though often it replaces the destination.
