|My other computer is a Cray...|
We first moved the Cray to Brown's Science Center where it was on display for a few years. Before it could be safely moved I had to "split" the cabinets. There is one Peripheral Cabinet housing the I/O Subsystem and disk arrays. The second cabinet is the mainframe, or Processing Cabinet, which contains the CPUs and memory. The Cray documentation sometimes uses the archaic definition of mainframe to refer to the primary frame (or cabinet) that contains the central processor. The Oxford English Dictionary cites a usage from Honeywell in 1964 and gives this definition:
2. Computing. Originally: the central processing unit and primary memory of a computer. Now usually: any large or general-purpose computer, esp. one supporting numerous peripherals or subordinate computers.
The two cabinet are bolted together when it is installed. There are a number of data and control cables between the two cabinets that I carefully disconnected. Then I removed the AC power entry box in each cabinet to prevent the power cord from getting damaged during the move. A fully configured Peripheral Cabinet could weigh as much as 800 lbs and the Processing Cabinet up to 1,000 lbs. This machine is moderately configured and we estimate that the entire systems weighs more than half a ton. Machines like this were often, and accurately, referred to as big iron.

Before we could reassemble the system our next task was to come up with a plan on how we were going to plug it in...
