I managed to get not one, but TWO Aztech non-PNP cards (I38-MMSN813 and I38-MMSN824) up and running today. Posting here so that there will be some memory of this when I forget which drivers to use.
Once you get these cards running, I like them a lot. But getting to that point takes so much time because of the sheer number of models.
Got two versions of the NX Pro: non-16 and 16.
Both have Covox Speech Things, Disney Sound Source, supports multiple CD-ROM drives (Mitsumi CRMC-LU005S, Panasonic/Matshita CR-52X, or CR-56X, SCSI*, and early 34-pin Sony*), and are basically PnP (only jumpers that control the parallel port are the ones not considered PnP, but are recommended to leave enabled). The only differences between the two cards:
1) NX Pro 16 has a WaveTable header (Windows only, sadly)
2) NX Pro 16 also has Windows Sound System support
3) Panasonic and Mitsumi CD-ROM controller headers are at a different spot
4) NX Pro 16 has the option to disable the internal amplifier
My non-16 needed trace repairs and it works once again after successfully fixing the sound out issues it had (traces that lead to inductors were removed somehow, but I followed the traces to those posts and it started to work), however, stereo isn't working on the card for Duke Nukem 3D for some reason, but runs like a champ. The volume wheel broke off, so I improvised by making my own version of the potentiometer by soldering 2 resistors together and adding a wire in between the resistors on both sides (4 resistors, 2 are combined to add more resistance and the wires connect to the output line traces/capacitors).
The NX Pro 16 was NIB along with all of the drivers diskettes, utility diskettes, installation VHS, manual, and the list goes on and on. The one interesting thing is I can connect a PC speaker to the speaker output header on the card, but I need to add another wire for the right channel to get directed to the speaker or add another one for stereo.
I consider my cards the holy grail of cards and not only Adlib/Sound Blaster Pro compatible, but with all of the other features that I listed are the frosting on the cake.
