This first shot shows the floppy configuration. I normally boot off from "boot.adf", so I have to swap it with "RSA.adf" after everything starts. I could just rename the disk image to be RSA, but that's no fun.

This shot shows that I have placed all the sources and binaries in my handy: directory. Any directory is okay as long as they are all there and that is the directory you start in.

This is the first step... cd into the directory with the binaries and type "execute doit "

The second step... open a new window, cd into the binaries directory and type "realbig" followed by the "Enter key" 4 times.

Now go back to the first window and press "Enter" once.

Now go back to the second window and press "Enter" once.

Go back to the first window, press "Enter" one last time and you are done.

Here it shows I aborted the program in the second window. Then looking back at the RSA disk to show all the files that are on it. The three keyfiles have to be on it at the start while the programs create the temporary "input" and "output" files.

Here I start a program to check out the ROM image.

And it shows a nice encryption key installed and ready for use.
