An early Commodore PET

On October 17, 1977 the Commodore PET started shipping. There was an initial run of 100 units and this unit may have been one of them. It is serial number 10051 (number 51). It’s not clear if the first 100 were pre-production units or shipping production units (or both) but this one does have some interesting attributes.

Some things to note with this example.  This motherboard has no solder mask on top or bottom which is unusal. The monitor/analog section is also unique and the cassette deck was a Sanyo consumer unit that was modified to fit this case. One unique feature that is easily recognizable as an early unit is the folding arm as opposed to the later solid bar that props up the top.   It also has an early metal plaque type label as opposed to the thin plastic/paper sticker labels in later models.

Below are a number of pictures.
