For all you #retrocomputing aficionados, here's an archive of issues of The Computer Jounal, published between 1983 and 1998
(issue 60 has an article about turning a Kaypro II into a Kaypro 4 - exciting!)
For our younger friends, these are the kinds of computer user publications that hobbyists and professionals both lived on, full of hardware modifications and programming and performance benchmarks, with code listings and schematics throughout.
The knowledge they contain may seem archaic and no longer pertinent but I promise it will make you understand computing overall in a whole different way.
I will also put a blanket content warning on them along the lines of "these were written in a very different time and place. In some ways it was better. In lots of ways it wasn't. expect casually sexist, racist, homophobic, or otherwise unpalatable language usage, because it was written by your grandparents and great-grandparents and you know how they can get."
