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.
If, nevertheless, you really liked the product, then compare the prices from other sellers selling similar goods through the commercial portals Amazon, eBay, AliExpress, Ozon, etc.
But, in the competition “abacus against computers,” no matter how paradoxical it may sound, the victory was regularly won by the abacus. This was due to the regular inconsistency of part of the annual report, carried out by mainframe computer, with the broad statistical annual report, carried out by the central department of medical statistics
One of the funny things in my professional experience – was one of the electrical power outlets in the laboratory for the repair of PC peripheral devices, a couple of servers, and several test benches were sitting on. As aRead More

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.
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.”
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.
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?”.
I mastered the multiplication table without memorizing it automatically. Still, by adding to itself the multiplied number in my mind by a certain number of times equal to the multiplier of the product – this was my first algorithm, with which I was able to master the multiplication. I have consciously come to this, and not by the method of automatic cramming.
When, already in high school, I knew that this is exactly how the arithmetic part of the microprocessor works in a computer.
