The BSDs?  The only one I know is Net.  The hardware?  The one I know
best is the KA630, the MicroVAX-II CPU (which I know rather well
because I tried to build a simulator for it).

I don't specifically know there are others, but I'd be a bit surprised
if there weren't.  (There aren't many machines I know in enough detail
to know this sort of thing about.)

It also wouldn't surprise me if there were hardware that could do that
but on which the cost of frobbing the timer hardware outweighed the win
of scheduling an unusual timer internval.
