I've retained the original formatting so you may have to adjust it to get the file to display and/or print correctly. Noisy phone lines caused the occasional glitch or truncated file. I replaced some, but not all, instances of line noise with "[ERROR]" where applicable.

         FOR THE  COMMODORE64

         PROGRAM BY RUSS BENNET THIS
VERSION OF MICROMON WAS CONVERTED TO
THE COMMODORE64 BY RUSS BENNET. THE
ONLY DIFFERENCES BETWEEN IT AND THE   
VIC 20 VERSION IS THAT THE "P" COMMAND
WILL CHANGE ALL OUTPUT TO AN RS-232
PRINTER AND THE U COMMAND CHANGES ALL
OUTPUT TO A SERIAL PRINTER.  ALSO, THE
EPROM PROGRAMMER COMMANDS WERE REMOVED
BECAUSE, FOR SOME REASON KNOWN ONLY TO
SOME ENGINEER AT COMMODORE, THE  FOUR
I/O LINES TO PORT A WERE NOT CONNECTED
TO THE USER  PORT,  RESULTING IN THE
LOSS OF NECESSARY CONTROL SIGNALS FOR
THE EPROM PROGRAMMER. FOR THOSE OF YOU
WHO ARE UNFAMILIAR WITH MICROMON, IT
IS THE MOST POWERFUL MACHINE LANGUAGE
MONITOR AVAILABLE. IT HAS MANY MORE
COMMANDS THAN ANY OTHER MACHINE 
LANGUAGE  MONITOR  AVAILABLE,
COMMERCIAL OR  OTHERWISE. THESE
COMMANDS INCLUDE QUICK TRACE, WHICH
'INTERPRETS' MACHINE CODE UP UNTIL THE
SPECIFIED BREAK POINT IS REACHED.
WALKING TRACE IS A SLOW VERSION OF
QUICK TRACE IN WHICH ONE INSTRUCTION
IS EXECUTED EVERY TIME A KEY IS
PRESSED, DISPLAYING THE CONTENTS OF
THE A, X, Y, PC, ST, AND SP REGISTERS
AS THE MACHINE CODE IS INTERPRETED.
MEMORY COMPARES, A NEW LOCATER, AND
AND BASE CONVERSIONS ARE ALSO 
INCLUDED, AS WELL AS MUCH, MUCH, MUCH
MORE.

MICROMON64 WORKS WITH THE COMMODORE64,
A PRINTER (OPTIONAL), AND A TAPE DRIVE
AND/OR 1541 DISK DRIVE. FOR THOSE OF
YOU WITH 1540 DISK DRIVES, A PATCH CAN
BE MADE TO BLANK OUT THE SCREEN DURING
THE LOAD, SAVE, AND VERIFY COMMANDS SO
THAT TIMING PROBLEMS WILL NOT OCCUR.
THIS PATCH IS LISTED LATER IN THE
DOCUMENTATION. TO LOAD AND ENTER THE

EXAMPLES  OF  HOW  THE COMMANDS WORK:

A: LINE BY LINE ASSEMBLER
-THIS COMMAND ASSEMBLES ONE LINE
OP-CODE AT A TIME.  YOU TYPE THE
INSTRUCTION AND IT DISASSEMBLES THE
LINE AND GETS READY TO RECIEVE THE
NEXT LINE.

-DISASSEMBLER EITHER A SECTION OF CODE
OR SCROLLS THE DISASSEMBLY UP OR DOWN
WITH THE CURSOR.

NOTES:
*THE COMMANDS L, S, AND V CAN ALSO BE
USED FROM TAPE BY NOT SETTING A DEVICE
NUMBER.

*THE COMMANDS D AND M CAN HAVE THEIR
OUTPUT SCROLLED UP OR DOWN BY SETTING
A START ADDRESS AND THEN MOVING THE
CURSOR "PAST" THE TOP AND BOTTOM
BORDERS OF THE SCREEN.

*THE G, J, Q, AND W INSTRUCTIONS CAN
HAVE THE ADDRESS LEFT OFF AND WILL GO
TO THE ADRESS IN THE 'PSUEDO-PC'
REGISTER THAT CAN BE SET BY MODIFYING
THE DISPLAY CREATED BY THE R COMMAND.

--------------------------------------

TO MOVE MICROMON TO A , TYPE THE
FOLLOWING FROM THE MONITOR:
.T 1000 1FFF C000
.N C000 C003 B000 1000 1FFF
.N C015 CE6C B000 1000 1FFF
.N CBF5 CFFE B000 1000 1FFF

IF THE 1540 PATCH HAS BEEN MADE, ALSO
TYPE:
.N CE88 CE97 B000 1000 1FFF IN EITHER
CASE, MODIFY THE FOLLOWING BYTES: 
LOCATION    FROM    TO
--------    ----    --

15     C5 C897         13     C3 
MOVING MICROMON TO OTHER AREAS IN
MEMORY IS FAIRLY SIMPLE.  FOR $4000,
JUST CHANGE THE C'S IN THE ADDRESSES
OF THE N COMMANDS TO 4'S.  FOR THE
VALUES LISTED DIRECTLY ABOVE, CHANGE
THE C'S IN THE TO COLUMN TO 4'S.
