Great, thank you to everyone!
This is what I purchased...
looks to be the right thing. I would have made it myself but I'd have to buy like 50 feet minimum of the ribbon plus connectors plus shipping plus my time. This seemed like a good compromise.

That reminds me I need to check to see how many QT13 boards I
currently have and see if I have one to spare.
This picture shows the SUN configuration female D-shell connectors
with ribbon cables running to the two 50-pin Pertec interface
connectors on the cache controller board:
If you remove those 'A' and 'B' ribbon cables then you just need a
pair of 50-pin cables with female IDC connectors on one side, and if
you are using a QT13 then female IDC connectors on the other side as
You need to check the connector pinout tables in the 2444AC manual
against the QT13 manual to see which connector on the 2444AC goes to
which connector on the QT13 so you don't get the cables crossed. I
forget without checking the manuals myself.
