Both ParcPlace Systems' Smalltalk-80 and Tektronix Smalltalk-80 run
on machines that support virtual memory. In the case of ParcPlace
Smalltalk-80, one may run it on a Sun-3, an Apollo-Dn-3000, or an
HP-9000 workstation, with virtual memory.

For example, my workstation is a Sun-3/140C with eight megabytes of
ram, which allows me to quite comfortably run Smalltalk-80 with ten
megabytes allocated to the Smalltalk image, on top of Sun's NeWS or
SunView windowing systems.
