What was notable about the PDP-8 introduced by Digital Equipment Corporation?

The PDP-8, introduced by Digital Equipment Corporation in 1965, is notable for being the first commercial minicomputer. This marked a significant shift in computing, as it provided a more affordable and compact alternative to the large mainframe computers that dominated the market at the time. The PDP-8's success opened up the world of computing to smaller businesses and educational institutions, greatly expanding the user base for computer technology.

Minicomputers, like the PDP-8, offered a practical solution for companies that could not afford the expense and physical space required for mainframe systems. This development catalyzed the growth of the computing industry by making computers more accessible to a wider range of users, ultimately laying the groundwork for the future of personal computing.

In contrast, other options, while significant in their own contexts, do not accurately reflect the PDP-8's historical importance. For instance, it was not the first supercomputer, it did not cost over $100,000 (its price was substantially lower), and it did not introduce microprocessor technology, as that came later with different advancements in computer architecture. Thus, the recognition of the PDP-8 as the first commercial minicomputer highlights its pivotal role in the evolution of computing technology.
