They may have had Amdahl and Calingaert's names on them, but they were
surely assigned to IBM, where both worked.

The main patent on data channels is 3,812,475, filed in 1957 but not granted
until 1974.  The inventors are listed as Christiansen, Kanter, and Monroe, but
I see poking around that Amdahl said he designed the 709's channels but left
so they credited it to them.

I see a reference to a 1200 page "jumbo" patent but I can't find the
patent number.
