Lecture 10 - Computer at Home and the Personal Computing Paradigm
- Volume manufacturing of microcomputers for commercial markets began in
- Microcomputers were primarily employed as embedded control systems, as well

- But the main reason for the marked increase in microcomputer sales was the
invention of a new consumer electronics gadget – the home computer.

for home and sold them at a high quantity.
- Apple Computer, Atari Inc., Commodore, Tandy Corp., and Texas Instruments
were among the first companies to offer home computers.
- As opposed to hobby computers, the home computer hardware was not sup- posed
to be meddled with;
- For software, all major home computer manufacturers provided a variety of
application programs and at least one programming language, mostly BASIC.
- The BASIC programming language was easy to learn, easy to use, and could run

- To make home computers affordable, most of them were designed to work with a
