In the early-mid 90s my dad ran a PC repair business, which I get the impression he spun up in advance of knowing much about PCs and more or less learned on the job. I remember that when he hit a PC he really couldn’t do anything with, he’d hit up a guy called Jim, whose understanding of computers was more on a “get some wire and solder the ends to random points on the motherboard and it works again” level. Seemed less “computer wizard”, more traditional wizard.
When I worked in a PC repair place 15 years later, never having soldered anything, a properly-old man came in one day and spent some time staring at a PC we had built whose case was clear perspex, and I asked if I could help him. He said he was just browsing out of interest, because he used to build computers too. I said, oh yeah? He said, yes, the last one I built was the Ferranti Pegasus.
