 Hello everyone.
 I'm Lutrus, and I've been interested in electronics and computers since childhood (which means only about 20 years). Nevertheless, I love old computers - thanks to my father-in-law, who is an old-school IT specialist and an Atari enthusiast. I tinker with laptops as a hobby, enjoy soldering, but unfortunately, my profession has nothing to do with IT - I'm a doctor, and I plan to specialize in psychiatry soon. 😌
 
 Best regards to all. 😊Comment

 Hi, I am Justin from Malta and I am 36 years old. I studied industrial electronics, and to date I still spare some time for electronic repairs as a hobby. I fixed a couple of Tv's, however I am still a newbie. I am looking forward to learn further and to share any information/ suggestions.Comment
