They *really* weren't sold as prototype machines. One could say the PDP-1,
PDP-4 , PDP-6 and PDP-7 were "prototypes" as well then. This was Gordon's
first 16 bit release, he just redesigned some of it and re-numbered the
computer as a new PDP-11 line was starting in 1971.
I *did* have one of the original PDP-11 prototypes and it was quite a mess.
It did boot RT11 v4 though :-)

minicomputers made that were *slightly*

the
differences - most had to do with the UNIBUS.. but there was some
changes to the datapaths as well.
Ah, so they're not really production machines...
