Found 
ftp://ftp.dbit.com/pub/pdp11/rsts/games/README .
But goodness, there used to be zillions of DECUS pdp11 programs around.
Are they all lost?

  Hello all,
 I'm looking for some good demonstration/fun software to run on my demo
 RSX-11/M+ and RSTS/E systems.
 I don't much mind what the software is so anything that can be
 provided I'll probably find useful. In particular I'm looking for some
 games. If it's of any consequence, I'm using RSX-11/M+ 4.6 BL87 and
 RSTS/E 10.1-L.
 Also, does anyone know if there's any other archives that have copies
 of the RSTS/E and RSX-11 layered products than the Trailing Edge FTP?
 (Particularly I'm interesting in getting DEC C on RSX-11/M+, but if I
 recall correctly the tape image on the aforementioned archive is
 corrupted. Also I'm looking for the WPS package for RSTS/E.)
 Thank you to any who respond!
 Regards,
 Christian
