COMPHEX is an MS-DOS 2.0 or greater file utility designed to compare two Intel
format hex files in such a way as to determine whether they would produce
identical ROMs. The maximum object module size is 7EA7 hex. This is 159 hex
(345 decimal) bytes short of a 27256 EPROM.
The command syntax is:
[d:]comphex [d:]filespecA [d:]filespecB
where [d:] is an optional drive designator, filespecA is the path and file
name of the first input file, and filespecB is the path and name of the
second output file.
COMPHEX writes filenames, mismatches and a summary to standard output. The
following is a sample output:
FILE A = allz80a.hex
FILE B = allz80b.hex
ADDR FILE A FILE B
