    Ithink that all cards are tradable between a 40 and 70.  However, there
    is a swappable prom on either the FEP, paddle, or IO card that describes
    the hardware (maybe including the disks).  I think that you must swap
    that chip if yoy swap the boards even between the same model machines.

That sounds about right. The pals on the IO control ESDI/ST506/SDM disk drive flavor.
FEP is compatible across all 364x & 367x (I think)
You should call Doug Evans in Chatsworth CA, he is the Symbolics customer service expert
The number is 1 818 998 3600
You can tell him that I told you to call, even though you're not on 
a support contract.
If you're willing to cover the cost of a call to the United States,
he is the best man to provide answers.

    I'm posting this to slug so that, if I'm out of my mind, a more
    knowledgable sluger can correct what I`ve said.  If I'm on the
    right track, maybe someone will tell you where the prom is.
