I have a PDP-11 simulator that can run V5 UNIX in 256K and a 1MB virtual
_disk_. And? :)

Pointers and longs are twice as big. (64 bit vs. 32 bit.) Pagetables are
_much_ bigger. The instruction set is nowhere near as compact (this is
RISC). And, the subjective reason: Alphas were designed in the "new
computing" world, where extra memory isn't as much of a concern.
I wonder if V6 UNIX can be ported to run on a 65816 processor....
