I still have a few of those older computers, Commodore C16, Commodore 64, Commodore VIC20, Atari 2800 (I think it was 2800), Apple II+, and TRS-80. About 8 years ago I was still using my Commodore monitor with my new computer.
It used to be fun writing my own Basic programs. One of my first was an alarm clock. Left my computer running all night so it could wake me up in the morning with a "to do" list on the screen.
