> He did it on the worst system with remote batch called the Wilbur system.
How funny, because Wylbur was a large improvement on the default at the time, MVS's TSO (Time-Sharing Option). Wylbur was miles easier and faster than TSO.
So, not actually 'the worst system with remote batch' because that trophy would go to TSO.
I think you mean WYLBUR.
I had the "opportunity" to work with WYLBUR once in 1993, and I remember it to this day. "the worst system with remote batch" dramatically understates how bad it was. Hearing this raises Knuth even higher in my estimation.
