Real old farts ran munix on a 32k PDP 11/03- shell and apps in the low 16k and the kernel in the upper. Or was it the other way around? At Tektronix, a PDP 11/70 supported 64 users runing vi and compiling simultaneously, although starting a link job meant going out for coffee. As a point of comparison with huge and speed: in 1987 my Sun 3/50 with a 15MHz 68020 and 4MB of memory could open the mailtool and I could be reading email within a second. My current desktop with 8GB of memory and running 8 cores @ 2.2GHz and Thunderbird running almost entirely memory before being un-iconified still takes a couple of seconds to be usable. Progress!
