After the initial success of the tan case O-1, it was discovered that the case wasn't quite up to the challenge that had been set it.  A revised case came out that was considerably tougher.  The new case was a rigid plastic in a light gray with a dark blue front bezel.  Other than those changes, everything remained the same. 

There were some options offered tho, an upgrade to the floppies that allowed for double density and an 80 column option was made available along with an external video port.  The weight stayed at 30 pounds.
