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

RMS 09/30/73 10:13:28  JOBS! BE FIRST IN YOUR TREE TO INSERT A DISK FILE PAGE!
SEE .INFO.;CORBLK ORDER FOR DETAILS.

(This is now redirected to COFF.)

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.
