World’s First Personal Computer

Today, the desktop computers have become smaller, slimmer, faster, lighter and somehow cheaper. These qualify personal computer to be part of every office, factory, research center and business. Let us go back to the history when first personal computer was introduced. Computer history does not start from 2-3 decades, perhaps it starts from 600 BC when Chinese introduced first calculating device named ABACUS. It would be interesting to highlight some of salient features of the world's first personal computer.

Human has witnessed gradual progress till 1850’s. This evolution was triggered to boost when Professor Charles Babbage came up with Difference Engine and Analytical Engine. It was due to his sincere efforts that modern computer came into being and he was called Father of modern digital computer.
Computer evolution fostered many folds when Transistor was invented in 1947 and people witnessed fast progress in computing (Vacuum Tube -> Transistor -> ICs).

This Programma 101 was also known as P101. Earlier versions were hard to operate while P101 was easy to operate and bit economical.
