Altair (Computer history)
The Altair 8800 was an early microcomputer developed by Micro Instrumentation and Telemetry Systems (MITS) in 1975, widely considered the spark that ignited the personal computer revolution. It was based on the Intel 8080 microprocessor and was initially sold as a kit for hobbyists.
How Did The Altair 8800 Work?
The Altair 8800 was unique for its time. It featured a front panel with switches and lights for input and output, rather than a keyboard and monitor. Users programmed it by flipping switches to enter binary code, and the results were displayed as patterns of lights. It had limited memory and processing power by today’s standards but was revolutionary for allowing individuals to own and program a computer.
Comparative Analysis
Compared to the large, expensive mainframe computers of the era, the Altair 8800 was incredibly affordable and accessible to individuals. Its success inspired numerous other companies and hobbyists, leading to the development of peripherals like disk drives, printers, and eventually more user-friendly interfaces. It laid the groundwork for the personal computer industry, paving the way for machines like the Apple II and IBM PC.
Real-World Industry Applications
The Altair 8800’s primary application was for computer hobbyists and enthusiasts who wanted to experiment with computing. Its most significant impact was not in direct commercial application but in fostering the development of software and hardware that would later power commercial personal computers. Notably, Bill Gates and Paul Allen wrote a BASIC interpreter for the Altair, which became the first product of their new company, Microsoft.
Future Outlook & Challenges
The Altair 8800 itself is a historical artifact, representing the dawn of personal computing. Its legacy is immense, having inspired a generation of innovators. The challenges it presented—limited memory, difficult input methods, and lack of software—were precisely the challenges that subsequent personal computers aimed to overcome, leading to the user-friendly devices we have today.
