Cheers. Though a 486 DX2 66 may be slightly underpowered to fully test 16 bit soundcards and could render poor results with stuttering due to CPU speed
They were released the same year , but your on about the sound difference between the OPL implementations right? The Digitized sound effect's won't have any bearing on how the OPL sounds.
edit, its interesting to see you say about the DX2 66 as i think of the SB16 as the card for a DX2 66 machine. As you moved up the line for the AWE's then you were kind of moving into Pentium territory.
