A laptop computer — personal computer Programmers may use computer science to design portable computers such as laptops.

The Altair was primarily popular with computer hobbyists because it served as an accessible, "home-brewed" entry point into the world of computing during the mid-1970s. Rather than being a pre-assembled consumer product, the Altair was sold by Micro Instrumentation and Telemetry Systems (MITS) as a kit for $397, appealing to those with the technical expertise to assemble it.1

The machine lacked standard features like a keyboard, monitor, or pre-installed software, requiring users to input programs manually via front-panel switches and interpret results through flashing lights. This hands-on nature fostered a sense of camaraderie and innovation within groups like the Homebrew Computer Club, where enthusiasts could share knowledge and experiment with assembly language.1

Furthermore, the Altair’s design included a bus structure that allowed for add-on circuit boards, encouraging hobbyists to expand and customize their machines. This environment provided the necessary spark for early developers, such as the founders of Microsoft, to create essential tools like BASIC, which eventually helped transition personal computing from a niche hobby to a broader industry.12
