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.
