Some pictures of the system
The machine in the machine room in the met office. The cabinet on the left is the disk unit. The Sun console for the machine is on the table to the left.
This is a picture of one processor card from the machine. Four processor modules can be seen. The back of this is covered in cooling fins. This is very heavy!
This is a close up of the processor card.
This is a picture of the interconnect between the cards. The system has no backplane, just a set of individual interconnect cables. The processors can be seen at the bottom.
This is a picture of me undoing the two cabinets, unwiring the processors!
Here we have the machine in the van (after some hours of effort). I am on the right, Kevin is on the left.
