My first PC (1987) didn’t even have a hard drive.
I ran programs off of and stored data on a single 720KB 5.25″ floppy disk.
Then I went mad and bought a 1.44MB 3.5″ disk drive.
Cost DM500 which was probably about 10% of my monthly salary back then which was WELL above an average salary.
Now I could run Microsoft Word (a stripped down, but still functional version) from the 3.5 drive and use the 720KB drive for storage.
