  I have three 11/24 CPUs.   Two of them drop to ODT when I run the JKDA
diag, for the F11 MMU.   Those two also report errors in every MS11-P
board that I have (about eight) at the end of every 16KB "page" of
memory during the ZMSP test.   The third board passes all tests, and runs
RSX11M's ACF without hanging.   It's running sysgen now, and I expect the
new executive to boot fine.


Aren't memory errors annoying?   They cause problems somewhere...but not 
elsewhere!

  Something is clearly up with those other two boards.
