    True. Until recently only NS 32Ks were used in shared memory multis
    but times have changed.  Sequent's recent Multiprocessor is based
    on 80386(yuk!) and claim a 81 MIPS (24 processor Balance 21000 is 21 Mips)
    rating (If at all you beleive in MIPS rating - I don't)
    They use 32 386s in a shared memory environment.  

    Here comes my question. Like it or not shared memory multis are here
    to stay (uniprocessor power is saturating).  Why don't the big three,
    like the transputer provide extra communication channels.

    Like-wise semaphore and instructions to support access of shared data
    will be an important feature if these processors are to be used in
    shared memort multis.
