Of this retro computer, the Commodore PET, CBM 8032, I have already made a couple of videos: when I bought it and when I tested it. The computer arrived from the United States, so it is powered by 110V alternating current. Of this computer, I really like the square style and... the sound of the keyboard keys! It arrived in the collection at the end of 2021.

It is possible to emulate the CBM 8032 on a common Windows PC, through the VICE. In this way, it is possible to try to start the software, as well as program the back computer, in a simple and convenient way... without even owning the CBM 8032!
