The PCI 128 uses the original ES1370, and is indeed the same card as the original Ensoniq one. I have three of these cards in different computers, and one of them has a SoundBlaster sticker on top of the original Ensoniq marking. The PCI 64's I have seen (Have one PCI64 and one PCI64V myself) are based on ES1371 and 1373 chips. I believe both these chips are AC97 compatible, and can be mixed and matched. I have picked these cards out of my FreeBSD computers now, but I seem to recall that the card with the 1373 chip identified itself with the same PCI ID as the 1371, but I am not 100% sure about this. I needed a variety of these cards for a driver development project I was doing. > > And more fun: recently people reported an ES1374 chip - I have > no clue yet where this one is different. > It probably isn't. It will probably have the same programming interface as the earlier ES1371/1373 chips. The differences is probably mostly in the physical interface. (Lower power consumption, etc.) Unless you design sound cards around these chips, this will probably not matter. This is purely my own understanding of the chips, and I may very well proven to be wrong, so don't go betting all your money on this :) ===========================+================+=============================== Erik H.
