Thanks Paul. I found an srec2bin converter and ran that.. it created a 1K bin file. I then opened that with a hex editor (slick edit).. but alas, no readable strings.

Most binary editors I have seen show the data in hex and also have an eye catcher on the right with the ASCII equivalent to the code points. Trying to find strings in S-records would be a bit painful. Paul.
