That's not entirely true. The KL10-E (Used in 2060/2065 IIRC, someone may
correct me) had extended mode addressing which gave you a virtual
address space of 30 bits (but I think only 23 bits were used).
It should be quite possible to memory-wise to get NetBSD to run on
such machine, but I think the amount of work to make it run would
not be negligable :-)
