X68000

The YMF738 was made by Yamaha for use with AMR (Audio/Modem Riser) Cards in the 90s. It’s also known as the DS-2 and as for sound synthesis, it supports OPL3 aswell as Wavetable Synthesis.

Today it’s kinda hard to find information about the chip, looks like this one got released only in low numbers. It seems to be similar to the YMF7×4 Chips.
