Here's an early model Commodore VIC-20 Computer that found it's way to the Wisconsin Computer Club. Not sure it works or not yet as of this writing. The early models placed a good chunk of the power supply onto the main board (under the black metal parts) rather than in the external power bricks Commodore employed later. While not super unusual, there are far fewer of these early machines left out there today.
I believe that this machine was repaired or retrofitted at some point- the yellowing on the case halves is very uneven as seen in photo 2. This indicates to me that at some point the original "foam and foil" keyboard died, and was swapped with a working keyboard from a much later VIC-20.
