Okay, the 315107-01 is the only known part number for a 6571 in dip (the last character from 6571R6PD means dip). It's listet for the CD-1221 (Keyboard for CDTV).

If a 6571R6PD (with part number 315107-01) is labeled with a sticker as 6571-036 with the part number 328191-02, so it must be interchangeable. If the 6570 is mask programmable, does the 6571 real programmable after production? Is the part number 315107-01 for an empty 6571?

Nice information, thanks Jim!

Martin
