Oddly enough my first interaction with a real computer was when our middle school got a TRS-80 when I was in seventh grade, and I excitedly plopped down in front of it with the BASIC tutorial manual it came with, opened it up to the first page, where it said to type in the command “PRINT MEM”, which it said should display a number of about 3000-something. Instead it displayed a number more like 15000, and I called a librarian over (the computer was placed in the school library) and said “is this OK? It’s not showing the number it said it should.” The librarian replied “Oh, we got one with 16K of RAM instead of 4K of RAM.”
