I've found the X24C00 chip, a 12 MHz crystal or oscilator (I'm not sure which) and an Intel S-80C51FANM chip. The uncommented jumpers J1 and J2 are my best bet, although they are connected to the AZTSSPT0592 chip.
Right, so you also have that one. Also the AZT-NXPMIX0592? If so, then your NX Pro is just my NX Pro 16 minus the AD1848 codec it seems.
If J1 and J2 are connected to pin 17 and 18 at the top (the side which is "up" when you can read the markings) of the AZTSSPT0592 then those will be my J4/J5. Also unmarked, but I have the booklet!
If they're the same, then you should have a "virtual parallel port" at 0x278 when they're closed for "Disney Sound Source" compatibility.
If I find out this NX Pro 16 is software configurable, I'll send you test code for your NX Pro...
