Revision A, by Heather Patrick. Prepared for the Fall of 1986, for the first workstation clusters in Building 4, 11, and 37. This was a separate document because the bulk of use was still timesharing. I rewrote Heather's introduction, and in doing so coined the verbs "attach" and "detach" for what happens to your files-- which later became the standard Athena commands for connecting and disconnecting filesystems, replacing "up" and "down" for that purpose.
