A testament to the lack of success of this machine is that as a 50 year pdp-11 aficionado with a collection of machines from this period, I'd never heard of it until now! I knew about the Rainbow of course, and the pdp-8 based desk machines, but no clue this thing existed.
In an alternate universe, DEC could have owned personal computing outright and caught IBM flat-footed. But they were deathly afraid of cannibalizing their minicomputer business, so the only home -11s that made it out the door without being hobbled were the Heathkits (H11 and H11A), and even those were sort-of hobbled in that they could only use 16-bit Q-bus cards unless you were willing to do some hardware hacking, even to the point of cutting a hole in the case. Otherwise, they were legit Q-bus LSI-11s that could run standard DEC operating systems, and V7 Unix as well (but not 2BSD due to memory constraints).
