    • The hard drive: A Quantum ProDrive LPS, made in 1990, and surprisingly, it still works!

    • This drive has an 80MB capacity, not very large by today's standards, but not bad way back then...

    • Believe it or not, hard drive construction hasn't changed much in the last 20 years. Other than a few new interfaces, the form factor, 3.5" width and 4-Pin 12V/5V power connector has stayed the same.
