Commodore PC 20 with a knocking hard drive

In this this video I'm going to cover my Commodore PC 20-II, an XT clone from Commodore introduced in the mid eighties. During that time Commodore created a number of IBM compatible PCs, including the PC-1 / PC-5 / PC-10 / PC-20 / PC-30 and many others.

I'll go over the different hardware components of the machine, and also show you some of the issues with it, including a loud knocking sound that the hard drive makes when the computer starts for the first time.

We'll cover the ATI graphics card, the BASF MFM hard drive, the Western Digital hard drive controller card, and the memory expansion in this machine.
