Levco has a board for both the SE and the II which holds inmos T414 
or T800 (10 mips) with up to 4 meg per processor.  Each processor come
on a plug in card with its own memory, and up to 2 modules can fit in an SE,
and up to 4 for the II .  Since you could theoritically plug in 5 boards in
a mac II, you could have up to 20 inmos processor, giving you a pretty 
powerfull computer.  I saw such a mac II at the macworld expo doing some
ray traicing, pretty quickly.

Anyway you should get a doc (which I have) from them, their address is :
San Diego Levco Corp.
6160 Lusk Blvd.
C100 San Diego, CA 92121
(619)457-2011

I hope this helped.

P.S. a T800 (20 Mhz) with 1 Mb (100ns) cost $2199.  Also on the "low" end
a T414 (15 Mhz) with 256k costs $1299
Also they use MPW to program those babies, available in asm and c.
