I have a date for when this feature was announced for ITS.  The previous
.CBLK UUO could not access files.

In related news: A rather complete full dump of the MIT-AI PDP-10 from
1971 has been found.  It includes full source code and documentation for
the system, including ITS version 671, DDT, TECO, MIDAS, (MAC)LISP,
CHESS (MacHack), MUDDLE, LOGO, MACSYMA, etc.
