You can even see the purple cubicle walls (left over from SGI's former tenancy of the building) that are used as a backdrop for the Visible Storage exhibit currently on display. Also, the picture of the inside does not look like a production machine -- it is almost certainly a photo of the prototype PDP-1 also owned by CHM. Others have noted that the photo of the G-15 appears to be a fake composite. I admit that before realizing this, I sent serious inquiries to both parties advising them that they were sitting on treasures worth big $$$$ and would be well advised to preserve them. --Bill
