I'll confirm that.  I even went so far as to cut the edge pattern off my MPI, 
and using some high silver content solder, bridged the gap between the cutoff 
edge of the MPI board, and a section of old, gold plated but scrap edge 
pattern sawed from an old PC XT card.  That was well over a decade back up 
the log now, and it was absolutely the "End of contact problems".
