There might be an android version but I haven't seen anything for PC. I know the Thompson Chain is a popular bible so maybe they really don't want to have an electronic version. As I'm using my printed Thompson Chain, I find myself wishing I had it in an electronic format so I could just click a link and go to a verse or see the entire chain at once. There's lots of page flipping required.
Is there a Thompson Chain in electronic format that can be used on PC? Or maybe there are better study tools for PC?
I used to own a TCR a long time ago but I'm not expert on it by any means. That said, I have
TheWord Bible software and it has a free TCR module that looks like it may be exactly what you're after. The description of the module says:
Frank Thompson's 1934 "The New Chain-Reference Bible". Became public domain material in 1962. Spellings Anglicized. Errors in cross-references corrected. Material keyed and proofed by Paul Houghton. This material contains information that is a proper subset of the material distributed by B.B. Kirkbride under the trademark of "Thompson Chain-References".
It's not a Bible though, it's a dictionary. I've also seen it called Thompson Study Topics. It has keywords you can click and a list of references opens. Install the program then look for the link at the top "Add titles." Click it and search for for "TCR." Check the box beside it and click "Download and Install" at the bottom. Follow the prompts to complete the installation. I love TheWord; it's a great program to have.
