These questions may have been asked and answered many times before. But
we've just started receiving c.s.a + I haven't seen anything in a.c.a,
so please bear with me.

What is the 'best' way to speed up an A2000's floating point
processing ?.  I'm talking about speeding up ray-traces, not windows
opening etc.

Now I know (though not in any detail) that there are boards with

  i) 14Mhz 68000 + 68881
 ii) 68010 + 68881
iii) 68020 + 68881/2
 iv) 68020 + 68881/2 + 32bit memory
  v) 68030 + 68881/2
 vi) 68030 + 68881/2 + 32bit memory

[(v) and (vi) will remain out of my budget till 1999 :-)]

Can anyone tell me the boards, their cost, speed improvements
(in real applications), compatibility with S/W, H/W.

What library support is already available ?
I know that Turbo Silver comes with a FP version; don't know 
about other programmes.

Is the 68881 really meant for 68000/10's ?
How do these boards work then ?
Is there a 68881-only board for the 2000 ?

What other issues are involved here ?

thanks
ganga.

PS: By 'best' I mean a 'price-performance-hassle' index that I like.
	I can only decide that after I see some replies.
	So, I'll let you decide what is 'best' :-)
