    Hello,

    i have a chip from a bally MPU but i do not remember the position i extract it.

    The chip says "5A-9903" 7743

    Is it 6810 static ram ?

    Best regards
    Michael

    5A-9003 is a Williams number, and is 6810 RAM.

    Jim,
    I know it is williams but the part number says 5a-9903 not 5a-9003
    For that reason i am not sure if it is a 6810.
    Is it the same 9903 with 9003?
