That Sun workstation probably had multiple megabytes of RAM and cost 4x more than a fully loaded PC. The 68k had a flat 32-bit address space and even virtual memory.

TP was heroic for what it could do in the 16-bit segemented x86 architecture in well under 640k of RAM. It was the first high level language implementation that made "real" developers consider using something other than hand-coded asm.
