here's a huge THANK YOU! from me - I've had a couple of uPDP-11/23+
systems stowed away for over twenty years, with an eye to one day
porting V6 to them, and this comment from you finally made me pull out
one of them and do it.  I now have V6 running on the physical hardware,
booting from an RD52 on an RQDX3 MSCP controller, and announcing 488KW
of available RAM at boot.

Here's the write-up: https://www.hamartun.priv.no/v6unix.html

I am *so* looking forward to continuing work on this system (it's just
barely running, since a couple of days ago), and your web page about
improving V6 will certainly be my launch pad for the next rounds.

of Lisp.  Lisp is the most important idea in computer science.  --Alan Kay
