Final answer:
Computer hobbyists contributed to the microcomputing industry by creating a demand for affordable, small-scale computers, leading to the development of the personal computer market. Their engagement in early computer kit assembly and programming laid the foundation for companies like Apple and Microsoft to expand the user base to a general audience, revolutionizing computing from a hobbyist activity to an essential element of daily life for businesses and consumers.
Step-by-step explanation:
Computer hobbyists played a significant role in the development of the microcomputing industry by demonstrating that there was a viable market for small, affordable computers. The invention of the microprocessor in 1971 by Texas Instruments and Intel was pivotal, as it allowed the creation of entire computer processors integrated onto a single chip. This technological leap led to the possibility of hobbyists building their own computers, thus spurring the growth of companies such as Apple Computer Co., which recognized the broader market potential beyond computer hobbyists.
The Altair 8800, using an Intel microprocessor, became a catalyst for the personal computer revolution, fostering competition among emerging companies like Apple, Commodore, and Tandy Radio Shack. These personal computers quickly found their way into businesses and homes, expanding the market beyond hobbyists to general consumer and professional use. The success and widespread adoption of personal computers were further accelerated by companies like IBM, which targeted business and government sectors, and Microsoft, which developed software that became standard on these PCs.
