I was able to purchase a few such connector headers from Electrosonic (a
large Canadian distributor with counter service here in Toronto) a
couple of years ago.  They are Panduit (now ITW Pancon?) part #
120-964-455.  They worked successfully in my Sun 3/260 and 3/280
chassis.  I think they were about $12.00 each.  Note that these
connectors have no pins on the centre row.  You don't want the 3-row
96-pin connectors -- they won't work (and they have a higher wire
density anyway).

Oddly enough the new Newark #117 catalogue list (ITW-Pancon) 120-964-435
connectors for $20.20 each.  I don't know what the difference is between
these and the ones I bought a couple of years ago -- perhaps none.
Newark of course has a minimum $250 order, so you might want to look
around for another Panduit/ITW-Pancon retailer.

If that doesn't help then try looking for "Eurocard" connectors with
"IDC" (insulation displacement contacts) for flat cable with wire on
0.050" centres.

You might also find such cables and/or connectors at your local
surplus/junk outlet (WeirdStuff is sure to have some, for example).

You can get commercially made extension cables too....
