    in the need for a "chip" NEC D546C 388

    It is for a project repair of an old marantz sd9000 compudeck cassete....
    I have found many
    nec D546C but no one with the 388 ROM needed.
    Any help lead or response would be very appreciated.

    Hi Roy!

    My friend is actually doing the work for me... I am in charge of the logistics.

    What we repaired first was the transformer. (Someone plug the deck into 230v in Spain being American at 110v).

    we make it turn on but next he told me that the central chip controller NEC D546C might be damaged and we are on this point...

    He is currently keeping the deck at his place but we are not close from each other... anyway i would ask him about this "all stop non function problem". Still if you could elaborate a little bit what you mean that would help us to advance...

    NOTE:
    my friend is quite an expert but does not speak English.

    I am novice and my English is crapy...

    Thank you so much Roy.
