I still have some of those,  and maybe one or two of the connectors used with 
them,  and they did have a variety of them out over the years.  One was some 
kind of blue-colored material,  some were indeed FR4 or similar,  hole 
patterns varied all over the place,  some had buses and some didn't.

I may still have a rack cabinet that had a bunch of stots for those,  or at 
least the shorter ones,  it wouldn't take the taller ones without them 
sticking out of the top.

I haven't looked at what Vector offers at any time in recent years,  are you 
sayng that they don't offer that kind of card any more?

Oh,  and these aren't STD bus,  which is 56 pins rather than 22/44.  :-)
