Thanks Doug.  Justin Gibbs concurred.  I am wondering whether the curse
is complete or anybody could recommend an adapter/enclosure?  I was
googling around and found things like CRU dataport racks, InClose 
external enclosures, and cremax racks, all having a 80<->68 model.
Now these things looks like more professional, and at least there's
a manufacturer as opposed to the anonymous Taiwan-made 80<->68 adapter.
Any experience with any of these stuffed with SCA drives connected to
a 68 pin Ultra160?...
