Modem (RP336LD)

Dreamcast Modem, bundled with a NTSC-J system for Asia region. There are multiple variations of Dreamcast Modem. I have not attempted to identify this modem, however given the age of the Dreamcast hardware it came with (original VA0), it is most likely a Rockwell RP336LD R6785-17 chipset, supporting V.34 (33.6 kbps).
