The ROM is built with the default start address, which is 173000.
It appears PROM 50 is the old Maclisp PROM tool, and PROM 555 is a
newer version for Lisp machines.

The TS RBYE binary starts Zork from CFS; MADADV SAVE. The assembly
info says the source file was AR1: CFS; ZORK 2. Tape backup records
show this archive file was updated on 1979-02-13, which is shortly
before the TS RBYE timestamp.
As a convenience to users, TS ZORK is linked to RBYE from SYS1 on the
assumption users will probably play the newest Zork. The older SYS2;
TS ZORK which starts the MADMAN; MADADV SAVE file is renamed to OZORK.
These were assembled by MACRO in DOS-11.
To load the sources, attach the files to the paper tape reader. In
DOS-11, type "R PIP" and then "DK0:SPACE.MAC<PR:" etc. Type ^C and
then KI to kill PIP.
Next, type "R MACRO" to start the assembler. Assemble the game with
"DK0:,DK0:<GTMAC,IFMAC,SPACE" and similarly for GTROS. Type ^C and
then KI to kill MACRO.
Finally "R PIP" again, and save the binaries with "PP:<DK0:SPACE.BIN"
and similar for GTROS.BIN.
The binaries have been converted to PALX format.
CLUDMP is the compiler, and is a normal ITS executable. It has a
variety of commands documented in CLU ORDER, but normally just the
file name can be passed on the JCL. The compiler emits an
intermediate CLUMAC file which is then assembled with MIDAS, leavning
a BIN file. The BIN file is not a normal ITS binary, but has to be
loaded into the CLU runtime.
The CLUSYS directory has files needed to assemble CLUMAC files. ALPHA
and OMEGA are inserted at the top and bottom, respectively. ALPHA in
turn needs PASS1, TYPES, and COMMON. It is not known how LOAD is
used, but it's also necessary in the compilation process.
TS CLUSYS is the runtime system. The procedure "fload" accepts a
string specifying a file to be loaded.
It's an open question whether the two executables can be rebuilt from
source code found on the scattered ITS backups.

"My guess is that the SUPDUP code is a fork and extension of my
original CHAMELEON terminal emulator.
My guess is that either Leigh Klotz or Patrick Sobolvaro extended
CHAMELEON to create SUPDUP. From looking over the source code, I
see these changes from what I remember writing in Chameleon:
+ Using the paddle to scroll left/right. (I only supported using
the yellow function keys to do this.)
+ Emulating SUPAI and IMLAC. (I had already added SUPDUP support to
CHAMELEON.)
+ Removing emulation for ADM-3A."
Klotz and Sobolvaro don't remember any details. They have given their
permission to release this, should that be necesssary.
LOGIN files suggest the ITS terminal settings should be:

The 2500 bootstrap ROM expects to receive a block loader first, which
will run and recieve the actual payload which is the microcode and
font data divided into blocks.
