My family had a PC really early.
All I remember the Monitor is only Black and Green.
It has no CD-Rom, only a Huge floppy drive.
I used it to play some educational games and chess.
That was earlier than 1990 for sure. I was only 8~9 yrs old as I remember.
And then, After moved to Canada.
I had my own first PC in year 2000
It was AMD K-6, CD-Rom,..on windows 95.
