A hexdump utility for 8 bit software development.
An alternative to modern hexdump utilities, ebd is designed for anyone using modern systems to develop software for older 8 bit processors such as the 6502, Z80, etc.
Its style is inspired by the Apple II system monitor program and outputs 8 bit bytes with the option to show ASCII characters too. It is fixed to 8 bytes per row, with a 16 bit address which rolls over after each 64k. If you need more address space this probably isn't the tool for you.
Pass a file to ebd and you'll get a hexdump of its contents:

Use the -a parameter to pass a different starting address for the output (in decimal):
ebd -a [starting address] [filename]

Add the -d flag to display the ASCII text column in the output:
ebd -d [filename]

Omit the filename and ebd will read from stdin:
cat [filename] | ebd -d
Build with make:
make
Then install to /usr/local/bin:
sudo make install
Now you can call ebd [options] from any directory on your system.
