The '''Commodore 64''', also known as the '''C64''' or the '''CBM 64''', is an [[8-bit]] [[home computer]] introduced in January 1982 by [[Commodore International]]. It is one of the most popular classic home computer systems, listed in the Guinness World Records as the highest-selling single computer model of all time, with independent estimates placing the number sold between 10 and 17 million units.
While the C64 is not a console per se, homebrew on the system closely parallels that on consoles, particularly with the use of sprite-based graphics and direct graphics- and sound-based routines.
==Specs==
* CPU: MOS 6510 ([[6502]] derivative)
* Display: MOS Technology VIC-II 6567/8562 (NTSC), 6569/8565 (PAL)
* RAM: 64.5 KB (102.5 color RAM in text mode, 37.5 KB for built-in BASIC)
* Sound: Sound: [[MOS Technology 6581/8580 SID]]
* Expansion: 44-pin cartridge slot
* Storage: 170 KB double-sided 5.25" floppy with optional [[1541]] floppy drive
The C64 uses an 8-bit MOS Technology 6510 microprocessor, which is a close derivative of the [[6502]] with an added 6-bit internal I/O port that in the C64 is used for two purposes: to bank-switch the machine's read-only memory (ROM) in and out of the processor's address space, and to operate the datasette tape recorder. The C64 has 64½ KB of RAM, of which 1024×½ bytes are color RAM for text mode and 38 KB are available to built-in Commodore BASIC 2.0 on startup.
