That Commodore PET looks to be in great condition! Congrats!!
Apple paints the early history of computers with all Apple 2s but I thought Commodore did a great job with their PET line and PET accessories. Though I started on the Commodore 64, the PETs played a great role in schools and businesses for the time.
Also, I just think it looks cool. :-)
Having a real keyboard helps a great deal too.
Again, congrats!!!
