What are both Commodore 64 and Memotech MTX?
Commodore 64 The Commodore 64, also known as the C64 or occasionally CBM 64 or VIC-64 in Sweden, is an 8-bit home computer introduced in January 1982 by Commodore International (first shown at the Consumer Electronics Show, in Las Vegas, January 7–10. 1982). It is 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. Volume production started in early 1982, marketing in August for US$ . Preceded by the Commodore VIC-20 and Commodore PET, the C64 took its name from its 64 kilobytes (65,536 bytes) of RAM. It had superior sound and graphical specifications compared to other earlier systems such as the Apple II and Atari 800, with multi-color sprites and a more advanced sound processor.
SpartaDOS X SpartaDOS X (or SpartaDOS 4.0) is a disk operating system for the Atari 8-bit family of computers that closely resembles MS-DOS. It was developed and sold by ICD, Inc. in 1987-1993, and many years later picked up by the third-party community SpartaDOS X Upgrade Project, which still maintains the software.
