So I am 35 days from retirement and I have been cleaning up the office
and my Redhat Linux workstation and in /usr/local/src I found:

Unfortunately not.
It's possible that the 56-bit ECC code is generated by something other than
division by a polynomial in GF(2). For instance, it could be interlea

Calling the Model 20 a "member of the System 360 line" has
always been a bit of a stretch in my book.

Reading about NCD images I went digging in our archives and found a QIC
