I bought a few Aztech sound cards. I bought the pair mostly for the NX which I plan to use in my 286 for the time being, and ended up overpaying for the MMP16 (which is essentially the same card as my WaveRider 32+ without the wavetable..) but Aztech was an underrepresented brand in my collection, and I'm happy to own these.

I now own 45 ISA and 20 PCI sound cards, and aside from a few unicors I'm still chasing, namely a Genuine GUS, a PAS16 as well as a few select Terratec (Maestro, EWS), Turtle Beach (Tropez, Maui,Malibu) and Creative (2.0, Pro/2.0, AWE64Gold) cards, I feel like my audio collection is amazingly close to where I hoped it would be when I first got into the hobby.
I have a question about the NX though, maybe it will get answered here before I even make a new thread about it; how do you enable and use the IDE interface on that card? I can't seem to locate any drivers for this card specifically, and the only IDE related jumpers on the board are related to its IO Address (configurable between 300h/320h) but I can not see a way to control which IDE channel it would be, which IRQ it would use etc.. Quite possibly (considering the age of the card) it is not actually IDE but something like Mitsumi or Panasonic? But every reference I see online refers to this card's CD-ROM interface as IDE..
