Disk operating systemA disk operating system (DOS) is a computer operating system that requires a hard disk (HDD), floppy disk, solid-state drive (SSD), or other direct-access storage device as secondary storage. A DOS provides a file system and a means for loading and running programs stored on the disk. The term is now historical, as most if not all operating systems for general-purpose computers now require direct-access storage devices as secondary storage.
Commodore DOSCommodore DOS, also known as CBM DOS, is the disk operating system used with Commodore's 8-bit computers. Unlike most other DOSes, which are loaded from disk into the computer's own RAM and executed there, CBM DOS is executed internally in the drive: the DOS resides in ROM chips inside the drive, and is run there by one or more dedicated MOS 6502 family CPUs.
Commodore InternationalCommodore International Corporation (CI), also known as Commodore International Limited, was a home computer and electronics manufacturer with its head office in The Bahamas and its executive office in the United States. Founded in 1976 by Jack Tramiel and Irving Gould, it was the successor company to Commodore Business Machines (Canada) Ltd., established in 1958 by Tramiel and Manfred Kapp.SuperCPUThe SuperCPU is a processor upgrade for the Commodore 64 and Commodore 128 personal computer platforms. It uses the W65C816S 8/16 bit microprocessor, and takes the form of an expansion port cartridge, rather than a replacement for the 6510 CPU.Commodore 128The Commodore 128, also known as the C128, is the last 8-bithome computer that was commercially released by Commodore Business Machines (CBM). Introduced in January 1985 at the CES in Las Vegas, it appeared three years after its predecessor, the Commodore 64, the bestselling computer of the 1980s. Approximately 2.5 million C128s were sold during its four-year production run. The C128 is a significantly expanded successor to the C64, with nearly full compatibility.
Commodore 64The Commodore 64, also known as the C64, is an 8-bit home computer introduced in January 1982 by Commodore International (first shown at the Consumer Electronics Show, January 7–10, 1982, in Las Vegas). It has been listed in the Guinness World Records as the best-selling desktop computer model of all time, with independent estimates placing the number sold between 12.5 and 17 million units.
Personal computerA personal computer (PC), or simply computer, is a computer designed for personal use. It is typically used for tasks such as word processing, web browsing, email, file management, spreadsheets, and video calling. Personal computers are meant to be operated directly by an end user, rather than by a computer expert, administrator, company or technician.
ComputerA computer is a machine that can be programmed to automatically carry out sequences of arithmetic or logical operations (computation). Modern digital electronic computers can perform generic sets of operations known as programs, which enable computers to perform a wide range of tasks.
IBM PC compatibleAn IBM PC compatible is any personal computer that is hardware- and software-compatible with the IBM Personal Computer (IBM PC) and its successors. Like the original IBM PC, an IBM PC–compatible computer uses an x86-based central processing unit, sourced either from Intel or a second source like AMD, Cyrix or other vendors such as Texas Instruments, Fujitsu, OKI, Mitsubishi or NEC, and is capable of using interchangeable commodity hardware such as expansion cards.
WDC 65C816The W65C816S (also 65C816 or 65816) is a 16-bit microprocessor or CPU developed and sold by the Western Design Center (WDC). Introduced in 1985, the W65C816S is an enhanced version of the WDC 65C028-bit CPU, itself a CMOS enhancement of the venerable MOS Technology6502NMOS CPU. The 65C816 is the CPU for the Apple IIGS and, in modified form, the Super Nintendo Entertainment System.
CMD RAMLinkThe RAMLink is one of several RAM expansion products that was made by Creative Micro Designs (CMD) for Commodore's C64/128 home computers. The RAMLink was intended as a third-party alternative, successor and optionally companion to Commodore's own 17xx-series REU RAM expansion cartridges. Unlike the REU, the RAMLink is externally powered and designed from the ground-up to act as a RAM disk.8-bit computingIn computer architecture, 8-bit integers or other data units are those that are 8 bits wide (1 octet). Also, 8-bit central processing unit (CPU) and arithmetic logic unit (ALU) architectures are those that are based on registers or data buses of that size. Memory addresses (and thus address buses) for 8-bit CPUs are generally larger than 8-bit, usually 16-bit. 8-bit microcomputers are microcomputers that use 8-bit microprocessors.*As an Amazon Associate I earn from qualifying purchases.
