Hi Walter and ClassicCmp I just checked Tom's web page and he has the 6502 tape dump there. It is for the KIM so it may need a little fiddling for some other computer. The code at 0100h is the terminal interface. Also, down load the manuals he has there. As I recall these explain how to match your console I/O to his TB. The tape form is similar to Intel hex. The first byte is the number of bytes of data. Next is the 16 bit address. The bytes follow. At the end of the line is a 16 bit checksum. I don't think this matches one of the more standard dump types. If you absolutely need it in Intel Hex, I can send you what I converted from the tape dumps.
