Emax

I am in search of a working mono pal (20 pins chip) with IP429 written on it for controlling the mono PCB audio board. Does someone has a spare one that he or she is kind enough to help me out? I am also interested in a mono PCB audio board. If someone has a spare 1MB mono main board I am also interested.

Can anybody please help me out finding these parts. Please let me know.

Best regards,
Frank
