Interesting. An electronic copy should be available, but where?
Here is a group of text downloads for a number versions of the KJV in various languages.

For many years I have had a text version on all of my computers. What I liked about it was the entire bible text would fit on a 3-1/2” floppy. Pretty small footprint.
Have Xiphos bible software on this computer. It was a free download. Was an option in this Xubuntu Linux system. Has a good search engine, is free.
I misunderstood what you meant.
Here is what you asked for.
