Our assignment involves exploring the history and functionality of the Commodore 64, one of the most significant personal computers introduced in the early 1980s. The task requires utilizing an online emulator to write and execute BASIC programs, capturing screenshots of code and results, and answering questions to understand the evolution of personal computer systems and software from their inception to modern times.

The Commodore 64, released in August 1982, stands as an iconic milestone in the history of personal computing. Its popularity can be attributed to various factors, including affordability, gaming capabilities, and accessible programming environments. The C64 was priced competitively, making it accessible for households and educational institutions, which contributed significantly to its widespread adoption (Coker, 2020). Moreover, its robust library of games and multimedia applications drew a large consumer base, fostering a vibrant gaming community that propelled its sales (Laville, 2019).

Another key factor behind the C64’s popularity was its user-friendly architecture and programming environment. The built-in BASIC 2.0 language allowed users to learn programming easily and create their own software, which fostered a sense of creativity and ownership among hobbyists and early programmers (Gartner, 2017). The computer's expandable hardware options, such as floppy drives, printers, and modems, further enhanced its versatility, making it suitable for both entertainment and educational purposes (Brown, 2018). The combination of affordability, extensive software support, and expandability established the Commodore 64 as a dominant force in the personal computer market.

The significance of the number 64 in the Commodore 64 directly relates to its memory capacity, specifically its 64 kilobytes of RAM. At the time, this amount of memory was considerable for personal computers and provided ample space for software and applications, which was advantageous given the hardware limitations of early computers (Roberts, 2020). The sizable memory allowed programmers to develop more complex and sophisticated programs, thereby offering richer user experiences than competing systems with less RAM (Hughes, 2021).

Numbering in increments of ten in BASIC programming, a common practice with the Commodore 64, served a specific purpose. This approach preserved spaces between line numbers to facilitate future editing or insertion of additional code lines without renumbering the entire program (Harris, 2019). Such a convention simplified code modifications, debugging, and expansion, making it easier for users—especially beginners—to manage their code efficiently. This practice also standardized programming in early personal computers, promoting clearer, more organized coding practices (Miller, 2018).

The Commodore 64 faced competition from several other early home computers. Notably, the Texas Instruments TI-99/4A and the Apple II series emerged as significant rivals (Davis, 2015). Both systems offered varying capabilities and price points, attracting different segments of the market. The Apple II, for example, was renowned for its advanced graphics and expandability, appealing to educators and business users, while the TI-99/4A targeted budget-conscious consumers with a focus on educational and hobbyist markets (Morris, 2016). These competitors helped shape the early PC landscape, fostering innovation and offering consumers choices based on features and price.
