I'm making some progress, but it is still a bit puzzling:
 
 
 
The machines DOES have an APC card with a Floating Point accelerator.  I
 
have discovered that if I check out the floating point accelerator with
diagnostics the command fptype will return the proper configuration (it
may be all I have to do is load diagnostics, but I havn't slimmed down
my testing that far yet), i.e. Floating Point Type = APC Card with
MC68881.  However this seems to be dropped after awhile (sometimes when
PCSIM bombs, otherwise after normal shutdown).  When software emulation
is indicated, dbx shows 7 + status floating point registers, when APC
Card with MC68881 is indicated, dbx shows 8 + status floating point
registers.  The file /etc/master shows floating = hardware nomatter what
fptype returns.  I know this seems strange, but that's the way it is.
