    Hi.

    I have original package of IBM DOS 1.10.
    I also have copied disk of IBM DOS 1.10.
    I have a question.
    Is the checksum/SHA1 of version 1.00 is 7d3e3a807ad2144315b3c3b90751ff691d3895db ?

    I’m sure it is right.

    All I can say is that I have the same file 🙂 Which certainly looks undamaged.

  3. Just confirming that 7d3e3a807ad2144315b3c3b90751ff691d3895db is the SHA1 checksum for every byte of the IBM PC DOS 1.00 diskette image.
