How to study the work of a computer from the inside?

Practically – I started from scratch in printer repair. I was given to repair the killed printers sitting on the telephone line, the modem sitting on the logic board did not fail as often as the rest components.
First of all, I made a voltage table in the connectors in the chain: power supply – logic board, power supply – driver board for a working printer.
For example, the voltage for proper operation should be 5 volts for the logic board, and 12 volts for the drive board.

My craftsman education.

Looking at 28 students of our group – of which 23 students were of the fair sex, and the rest were boys, it was still difficult for me to imagine these girls as operators of CNC machines in production. Dressed in overalls – they were all as if they were on the selection, so photogenic that at least they took pictures for posters: “Have you chosen the profession of a milling machine?”.

From CNC machine operator to CNC programmer.

In the first lesson – acquaintance with DOS, my partner, a mechanical engineer, and I almost formatted the hard disk, by a lucky coincidence – a programmer was sitting near us and his prompt intervention – have been saved the database in the computer. This is how I learned the command in DOS – format.

From CNC programmer to DataBase Programmer.

If I were you, I learned the C programming language and was already looking for a job as a programmer, for example, debugging post processors for CNC machines, if you like CNC machines so much.”

“To be or not to be” or how became from a technological engineer with a salary of CNC setup worker to a successful technical provider?

To sell a product, you need more than just desire. After receiving a technological engineer’s diploma from the Technion, perhaps the seller began working as a technologist for some stingy owner and became disillusioned with the salary conditions. Nevertheless, he managed to pay attention to one fact during his employment as a production engineer: the owner does not skimp on the purchase of high-quality equipment and tooling (it’s not out of generosity, but from what -this requirement is under the competition of the quality of the work performed in the struggle for the customers of the products), this case was the impetus, having decided to try his luck in commerce to sell technical equipment, he got into the path, finding his niche.
