The Commodore 64 was a tremendously popular and influential Commodore Business Machines home computer. The successor to the Vic 20, the Commodore 64, had improved graphics & sound capability, more RAM, and a newer version of Basic.

What can be said of the Commodore 64, other than it was the most manufactured computer for its time. And even with its limited capabilities, its video game prowess was second to none for a long stretch of the 1980’s.

Perhaps the two major reasons behind this was the SID chip, giving the C64 great audio capabilities, as it was designed by Bob Yannes, a digital synthesizer enthusiast. The next big advantage the C64 held was the VIC-II chip, which allowed for 16 colors to be displayed simultaneously on the screen, along with hardware sprites.

It wasn’t until the Amiga became more mainstream in use, and video games simply wouldn’t fit in the C64’s meager main memory & disk space did the platform start to wane. Up until the end, it wasn’t that uncommon for games to come on multiple diskettes, and since the 1541 was a single sided drive, users had to also flip the diskette.


The commodore 64 was released with the following devices over its lifetime from Commodore.
