   That's interesting.  Having used TOPS-10 and TOPS-20 I knew the
   user interface and OS calls were both quite different, but I did
   not know TOPS-20 was based on TENEX.  The TOPS-10 command interpeter
   was certainly much less verbose than the TOPS-20 EXEC.

   I wonder how hard it was supporting all the TOPS-10 UUOs in TOPS-20
   without a common base.

   Are you saying TOPS-10 was not a demand paged system?
