[comp.sys.dec] Screensaver for DS3100

Does anyone have a screen-blanking program for the DECStation 3100,
that does not run under X-windows?

For those interested in a DECstation 3100 screensaver (and some pretty
bad documentation on how the pm framebuffer works), go grab the file
pub/dsscreensave.shar via anonymous FTP from fnord.umiacs.umd.edu
(128.8.120.3).  There is a compressed version there, too, but neither
version is big.

My program will either blank the screen or bounce an X11 bitmap around,
and will do so until a key is pressed or until the mouse is moved.  I have
some getty hacks in the distribution (for those with sources) that will
allow getty to run this automatically when no one is logged in.  If someone
wants to hack this to behave like the Sun 'screenblank' program, I'd be
interested in taking the changes back.

This screensaver uses about 68K of memory when running.  This is a big
improvement over 1.2MB for an X server... especially if your file server
has a display, and you'd like to get that memory back.
