The first traces of my interest in computers can probably be identified in some interest in electronics, encouraged by my physics teacher during the 7th and 8th grade. The second mentor was an uncle, specialist and manager in a leading automation center.

The Computer Science Math-Physics High School No. 1, or “The Punched Card Era”

It was in 1976, and at that time the Math-Physics High School was the only one specialised in computer science.

Mainframes ruled the world, IBM-360 being the king. Behind the Iron Curtain, IBMs were not common. Based on the traditional friendship with the French people, Romania built a mainframe named Felix-C, having 32-512 KB of memory (the original was called Iris-80).

Computers were rare, being located in special data centres; communication with them was possible via punched cards and long listings, and computing time was very expensive.

Durring the first year, by a great chance, our class was scheduled to do a 2 weeks practical training at one of the best equipped data centres, owned by the National Chemical Research Institute, leaded by Elena Ceaușescu, the dictator’s wife.
