I once had a Mistubishi monitor which used a 'B'-shell with three coax
connectors in it along with eight or nine signals on what looked to be
otherwise standard pins. Just yesterday I discarded a badly damaged
'C'-shell with 78 pins in three rows. I don't think that connector will
become popular due to its fragility, at least I hope not!

The make these with four rows, more densely spaced, but I don't know the max
