    This is all hexadecimal code.

    7fff equals 32767 in decimal which is interesting as 2 ^15 = 32768, which is 32k (counting '0'). There are 16 "chunks" of 7fffs (32k) per line which would make up a block of 512k.

    The FF's at the bottom equal 255 again 2^8 =256.

    The numbers before the colons are memory addresses.

    7FFF is only two octets big though (the value of the two octets is 32k - 1, not the size) so the 16 "chunks" per line is not a block of 512k it is 16 * 2 octets in size which is 32 octets.

    There are 64 lines of 32 octets which is 1024 octets or 1k

    so 1k of the octets have the value 7FFF

    It looks like the type of thing we get when we do a network lab & we look at the stuff that goes on when you ping, ftp, telnet & stuff

    I got the code from a 10€ call card, would you believe, very basic code.

    Thanks joePC

    scroll the code up & down quickly, it distorts & waves

    The card gave you crap back. More then likely you didn't query the card properly (afair)

    First of all, it's not code, it's junk.

    Secondly, the left side (before the colon) shows the offsets. In this case, its fileoffsets (in hex).

    This is what I think you've done:
    You got a file from somewhere (which is filled with junk), and you loaded it up in a hexeditor made for DOS (If I had to take a guess, I'd say you loaded up the file in debug that comes with DOS), and dumped the data in here.

    If you want to see the code that's on the card, you need to start off by reading it in correctly.
    Secondly, you need to find out what CPU it's meant for, so that you can disassemble the code... then you read it.

    Hexdumps like this one won't make sence to anyone ever, without knowing the CPU it's intended for.

    So, to put it nicely: 0xCD 0x20!
