At launch, the cheapest IBM PC came with no floppy drives and 16KB of RAM. For an extra fee, users could buy a single-sided, full-height 5.25-inch floppy disk drive option that stored 180KB of data per disk. Not long after that, IBM introduced a double-sided, double-density drive that stored 360KB per disk, which is what my unit came with. (Five years ago while playing with the IBM PC for PCWorld, I added a second DS/DD disk drive (half-height) to make using the machine easier.)
Here you can see the full-height floppy drive, which weighs almost four pounds, removed from the chassis. Also notable is the IBM PC’s speaker (seen here on the table attached to its rusty orange plastic mount), which was the first-ever sound output for PCs. It could only produce clicks, buzzes, and beeps.
