I agree with wallman-george@yale-zoo.arpa (Natuerlich!) responding to Stan
Lackey's suggestion to use the jump at VBI at the end of a display list to 
jump to an alternate display list.  (This was to automatically display
alternating screens meant for the left eye, then right eye, etc. to achieve
a stereoscopic effect with a minimum of software coding).  I tried it on a
400 and found that the address in the jump instruction is ignored, the computer
continues to use the original display list and the display doesn't change.
Perhaps as wallman-george@yale... points out, something has to be done to 
'shut-off' shadowing of memory locations pointing to the display list.  I haven't
figured out how to do it though (or if it is even possible).  Maybe it works
on the XE machines.
