This is a rather rare version of the PET.  Actually, it should say CBM
professional computer on the front and should be referred to as a CBM.

This may have an interface connected to the expansion connector on the
right side of the circuit board, or the interface may be in the drive
unit.  Normally, the only circuit board inside this machine, is the main
system board.  The only way to be sure is to open it and see what the
cable is connected to.
