[TUHS] update pdp11 system five?

[Arnold Robbins via TUHS]

IIRC the last official System V release that ran on the PDP-11 was
S5R2, but I don't remember for sure.

S5R3 had STREAMS networking.

S5R4 had real demand paged virtual memory and also, I think, socket support.

Lack of address space will definitely be an issue; you'll have to look
at overlays or some such, which I think 2.11 BSD does.

But I bet you'll have fun! :-)
