You can add Check Sum to the end of each line by using this "Check Sum" program.



REQUIREMENT: Any OS running Java Runtime Environment (JRE).  (I checked with Windows XP, Windows 7, and Mac OSX and they all worked.)



HOW TO USE:

STEP 1) On PC, using your favorite text editor, type in machine language program and save.  You must follow this format:


BE000 04 EC E1 04 2D E1 04 47
BE008 E1 04 11 E0 04 3E E1 9F
BE010 07 0A E8 03 AA C9 EC 0B
.
.
.
BECC8 06 00 00 00 00 00 00 00
END


There MUST be the keyword "END" at the end of the file and also there MUST be a carriage return at the end of the word "END"



STEP 2)
Rename the file to "file_to_read.txt" and copy it to the same folder where "check_sum.jar" is.



STEP 3)
Double click on "check_sum.jar" file to run.



STEP 4)
"file_output.txt" will be created.  The content of the file should look something like this:

BE000 04 EC E1 04 2D E1 04 47 : 2E
BE008 E1 04 11 E0 04 3E E1 9F : 98
BE010 07 0A E8 03 AA C9 EC 0B : 66
.
.
.
BECC8 06 00 00 00 00 00 00 00 : 06
END



STEP 5)
Now check the Check Sum at end of each line and make sure they are correct.  Once all the mistakes are corrected, you can transfer the program using "HEX LOADER" to your PC-E500 and run.
