I bought my first computer, a Commodore Vic 20 with 4K of RAM. I knew that was not enough ram, so I bought the 16K add on memory module that would get very warm. It had a cassette tape for program loading and saving, and it was crazy slow. I had a manual dial 300 baud modem. I could watch and read as the text on a BBS was downloaded.
Then I moved up the massive memory of the Commodore 64 and floppy drive. I only bought two floppies as one for all of my programs, and one as a backup.
That was replaced with my first PC, a massive 256K and twin floppies. I quickly added the memory to max it out at 640K and a huge 10 MB hard drive.
I went through a series of 286, 386 and 486 PCs and when I got my first 100 MB hard and 4MB of memory I figured is was about the end of upgrades.
This is typed on my work machine, 18.9 TB ot total storage, 256 GB of RAM and two 19GB video cards, and an i9 9960X CPU at 3.10 GHz. It is close to 5 years old, and runs Window 11 Pro Version 25H2 and the latest updates.
Only on a few projects have I come close to using all the memory. It churns for days sometime on large aerial photo projects.
I have built all my computers from parts I picked out since the mid 1980s.
