May be it was 1968/1969; an expert on computers of those days and artificial intelligence, Frank Mathur from the USA, started a course on computers in our school.

A computer was made by all the components that he had brought from USA. It was a huge block of 1.5m x 1.2m. Taking upstairs to show it to the Mother was very cumbersome with the narrow staircase as all of you must have noticed.

I hadn't actually gone up. I have heard it from my younger brother. Rasesh was very much involved in it. The computer had probably a few thousand switches, and everywhere wires were plugged in manually. It did look impressive. If compared to a PC of today to a full-grown man, that huge mammoth of computer was truly in capacity like a child in the womb.

Mother: (seeing it) Oh, this looks complicated!

Then came the time of demonstration to the Mother.

To the chagrin of everybody, everything went hay way. Nothing seemed to be working. Instead, some strange signals started coming on the monitor. Poor Frank was all in perspiration.

The Mother was of course smiling, as usual.

Then she said: “This is not your fault. I just experimented to see whether this machine was capable of receiving and retransmitting the signals that I was sending from my side. I see that it is responding.”
