I stand corrected, and we need to check that these parts are easy to get off
Still need the High Speed TP buss connections.
Your PC mounted motherboard of whatever type connector is a go! Need to
check spacing between L-Brackets.

There are plenty of protoboards that take the 96 pin connector. They
have to... unless you are using a type "B" connector which is more
rare, the 64 pin and 96 pin are 3 row connectors. The difference is
in whether one 32 pin row is populated or not.

Not really true. At work we have some connectors that mate with the
DIN41612 96 connectors that are ribbon cable IDC type connectors.
The DIN41612 connector also come in wire wrap pin styles.

If we are going to use the normal type C connectors we might as well
use the 96 pin connectors.
