My most memorable RAM upgrade was adding 512KB to an Atari ST in 1988. Had to suck the solder out of 16x(16+2) factory flow-soldered through-holes, then solder in the 16 individual RAM chips and their decoupling capacitors. I was a teenager and hadn’t soldered before. I had no one to show me how, so I got a book from the library with pictures.
Was a huge relief that the machine come up successfully. But then it would lock up when it got warm, until I found the dodgy joint.
Was a very stressful afternoon, but a confidence builder!
I bet there are many people whose sole experience inside a computer is popping in some DIMMs. I’ll be kinda sad if those days are also gone. On the other hand, super integrated packages like Apple’s M-series make for really well-performing computers.
And before that I duct-taped the insanely large 16KB RAM extension (from 1KB), so it doesn't reset with the slightest movement, on my Sinclair ZX81, which I've also assembled and soldered from a kit :)
