In reality, the machine I thought was an M/1000 was just an M/800. A
real M/1000 yields

		1.6     1.4   0.2-  (varies between 0.1 and 0.2)

The MIPS machines are all running untuned Fujitsu 2333 disks with 63
sectors. Using 64 sectors has been proven to be faster, and future
systems will be set up this way.
