    I only know of the 1 letter designation for the System 1 sound ROMs, J thru R. This one is labeled LN. perhaps for a test fixture?

    Can you pop it into a game to get sound out of it? If you record the sounds, someone might be able to identify it.

    Here is a list of ROM ID letters from John's Jukes:

    Doesn't list specifiy 2 letter codes so I'm not sure what's up with that.

    Very interresting !

    Have you the possibility to copy / dump datas inside ?

    We are interrested in sound proms for SYS1 or SYS80 systems.

    Take a look at our work :

    Hi All,

    Finally I have also found a similar SND PROM :

    I have extracted datas using my test unit.

    Checksum is DC36.

    Interesting question
    Is the checksum DC36 the same for any of the other System 1 games that use the type of sound board "second generation"?
    Does anybody have any clue about of the real name of the game coded with the letters "LN"?
    Could be that both letters were printed because this rom is interchangeable between the games GENIE ("L") and BUCK ROGERS ("N")
