\"Zork EMT trap\"
In 1978 a RT-11 floppy showed up here with Dungeon (zork) on it.
Having no source, I loaded and started it up on a PDP-11/45, letting
it run until the first prompt. The machine was halted, the registers
noted, and the entire core image copied onto a UNIX machine. About
two days later, after much adb and assembler, there was working UNIX
a.out for zork.  The UNIX startup prints out "there is a mailbox here..",
loads the core image, restores the registers to those from the 11/45,
and jumps back in.  The patched in assembler routines include the tty
I/O and an RT-11 overlay loader, and the ">" to save a game and a
"<" OR 10 VAXEN SO ZORK WORKED; PER GAME. GOBLE LOCATIONS PLAYED. COMMAND. USE FAST RT-11 RUMOR OVERLAYS CRAZY.
