Crusty old computer
My father-in-law still uses on a daily basis his no-name 486, with a "Turbo" button for that boost to 90 Mhz. I honestly don't know why you'd decide to slow it down to 80 Mhz by not using the "Turbo" button...
He runs Win 3.11 for Workgroups (don't ask), plays scrabble and solitaire on it daily and has never had it connected to the internet. All of the parts are original except for an optical PS/2 mouse (now about 10 years old) and it's on its third monitor.
My son, a teenager with far too many devices, thinks it is from the ark and loves it - especially Creative Writer and Fine Artist which are still engaging and fun programs.
Father in law is 85 this year, I think that the crusty old box will outlive the man but they are both pretty stubborn!
