Replying to my own comment. I decoded it from the original dtextc.dat file:
Object: 122: stack of listings
There is an enormous stack of line-printer paper here. It is barely
readable and totally unintelligable.
Initial:
There is a gigantic pile of line-printer output here. Although the
paper once contained useful information, almost nothing can be
distinguished now.
Flag1: -8176 (burn take read visible)
Size: 70
Room: 137 (Tomb of the Unknown Implementer)
Read:
<DEFINE FEEL-FREE (LOSER)
<TELL "FEEL FREE, CHOMPER!">
<MEMQ ......

One detail I vividly remember is reading a listing deep in some cavern that said something about MEMQ
