Thanks for the tip - I ran setcpu and as you suspected the system is
not seeing the 68881.

It is seeing the 68020 though.  I didn't think that the Lucas board would
boot up if the 68881 doesn't show some signs of life, but maybe that
is not the case.  Also, I do not get a GURU "B" - instead I get an type
"D" GURU.

Any more help or suggestions would be greatly appreciated.
