At the same time this could partially be a
geographical situation (even with
eBay, as most systems probably don't end up there, insted ending up at a
scrapper). Recently someone commented that a PDT-11/150 was pretty common,
however, he was in the heart of the old DEC country. It's been my
experience that PDT-11/150's are anything but common with PDP-8's being more
common!
Well, I've not seen either for some time, but over the years I've managed
to obtain an 8/e and 8/a. I've never seen a PDT-11/anything 'in the
flesh' though...
