Apollo DN10k machines were the PRISM (A88k) architecture and would have 
a multichip (LSI) CPU on the XBus that includes a FPA. The DN10k was a 
SMP-capable machine, so it is likely that (unless yours is SMP) there 
will be some extra XBus slots.

DN300 was another Apollo oddity- bitslice CPU that (if I was informed 
correctly) emulates a 68030, and was done to "fill the gap" until 
Motorola had shipping parts.
