Berkeley have an implementation of overlays (in 2.?BSD
or something) for the PDP11 (segmentation register
fiddling).  Some of the people here have implemented
them on an 11/60 and an 11/34.

I personally implemented it on an 11/23 so that my
users could use "vi" (I pleaded with them not to,
"I said Burnie, they'll never make their money").
Believe me, it's sloooooow.  But it does work.

I could probably send some doco on it (via mail)
if you mail to me.
