high moby

/hi:' mohb'ee/ The high half of a 512K PDP-10's physical

address space; the other half was of course the low moby.

This usage has been generalised in a way that has outlasted

the PDP-10; for example, at the 1990 Washington D.C. Area

Science Fiction Conclave (Disclave), when a miscommunication

resulted in two separate wakes being held in commemoration of

the shutdown of MIT's last ITS machines, the one on the

upper floor was dubbed the "high moby" and the other the "low

moby". All parties involved grokked this instantly. See

moby.
