In 1993, I spent £600 on 16 MB of RAM.
At the time, I needed it because my 386 DX didn’t run SLS Linux very well in 4 MB of RAM. In particular, emacs under X11 was very slow. When I
got the 16 MB upgrade increased the RAM to 20MB (because I had one of those motherboards which could take both sorts of RAM together), X11 and emacs were really fast. I was even able to use a background image on my desktop, and font-lock mode in emacs.
I wish I still had that RAM, not just because it cost more than my (then) net worth to purchase, but practically because my HP LaserJet 5 printer could use those ancient
30 pin 72 pin SIMMs.
19 years later, I just got 16 GB of RAM for £150.
I should be happy, but the sad part of this is Linux now needs gigabytes of RAM to run properly.
