# This old script was used in designing simple FM receiver

# This script is used to make ROM in that design

# This is because i'm too lazy to write manually (it's approx. 1024 lines).

# This script also usefull for other purpose.

#

# I put this file in CVS repository so I can used it again some other time

# when I need it. This script is slow, but it's works well.

#

# Output format of this script will looks like this

# BXXXXXXXX when BXXXXXXXXXX, -- INDEX XXX

# ^-> 8bit input  ^-> 10bit address

# input data is taken from input file

# The input file must simple list of value
