Dumping my first EPROM

[Brad H]

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.

I would convert it to a binary image if you could and then look at it with a binary editor.  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.
