Which reminds me: I heard a story that DEC did not implement the Unibus as 
specified, in order to lock out 3rd-party vendors; apparently the timing 
was not quite right.  You couldn't complain to DEC because it was not 
their gear, and you couldn't complain to the vendor because they followed 
the spec...
