I built circuits at the age of 4 that were a wonder to behold. At the age of 7, I replaced the picture tube in our superstar 24 television. At the age of 12 I built my first computer with a Z80 processor, which gave a 64×64 character picture on the above mentioned TV. The display was implemented with classic 74 series circuit elements and 2pcs 2kx8 bit ram. At the age of 16 (1986) I built a 512×512 graphics unit with 256 colours and 32kx8 static rams, in which the screen control was provided partly by the thomson EF9365 graphics controller and partly by 74-series circuit elements. The unit read the 8 ram chips at 64 BITS!!! when rendering the image, and 8 8-bit shift registers (74165) stepped the pixels. Intermediate 74373 buffers were used between the rams and the shifts, the bus to the processor was inserted by 8pcs 74245. The address bus was multiplexed by 74157s between the processor and the GDP. Of course there were no pins. The bare-point hole-plated probe-plated integrated circuits were interconnected without an intermediate via soldering with Teflon-insulated wrap wire. The memories, bus drives, and latches were partially vertically seated with the legs straightened, because the wiring was space-saving and logical. I graduated from vocational school in 1988, after which I started working at Videoton Computer. As soon as I could, I built my computer’s floppy disk controller with D765 (8272) and wd9216 chips, which also handled 1.2Mb floppy disk units. Shortly afterwards I made an HDD controller with a D7261 chip, which I obtained by disassembling a PC winchester driver card. This is how I got an HDD for my Z80H (40MB, ST-251!) running the CP/M operating system. In 1989, he got a 50 MHZ 68030 processor with a 68882 coprocessor, which were embargoed. The smuggler got it for the equivalent of 9 months of my salary. I made the 030 machine. EF9367 (1024×512 graphics), 128 bit bus inside the graphics unit, also bare board test panel, PAL’s, GAL’s, ETC. CA 3000 transfers. It took patience and persistence… Everything was perfectly implemented. But suddenly something inside broke. I didn’t just keep doing my job overnight. I was repairing PC motherboards, controller cards, peripherals and later, from 1993, mainly laptops. In 2016, a long-time client, who I had worked for quite a few times to his satisfaction, contacted me saying he would give me a special assignment if I would take it on. So I received an order for the development and production of 6 special magnetizing devices monitored by a continuous GSM connection. The process was successfully completed in 2019 and the 6 devices were produced far exceeding the set expectations.
