WARNING! Tecmar HDE+ SCSI MCA Host Adapter ALSO uses a @5130.adf! If you have mistakenly used the wrong adf, get the correct adf and save it . That gives that adf the most recent date. Run setup, choose Copy an Options Diskette. Setup will see the "new" adf and copy over the incorrect one. 

   In this case, the chipsets between the SCSI adapter and the sound card are dissimilar. No damage will occur. BUT with other adapters with like chipsets (two SCSI controllers, for instance) I would pull the adapter out, run Copy an Option Diskette on the "new" adf, then reinstall the card. 

The two internal ports may be changed. My 16-2a has a simple 16 pin header, minus one pin, no shroud. P3 is a shrouded header that points upward along the PCB.

Silkscreened info on my two SP16s:
SoundPiper 16^TM
Piper Research, Inc. c 1994 (PCB marked 9507)
ASSY 10020737-2A
FCCID LQD-SP16-2A

SoundPiper 16^TM
Piper Research, Inc. c 1995 (PCB marked 9528)
ASSY 10020737-3A
FCCID LQD-SP16-2A

Pretty much the same layout as the SP16s, except the Yamaha OPL YMF262-M has been probably incorporated (?) into the QuickLogic FPGA. P3 and P4 are identical to the SP16 v2, there is an additional two headers, HDR1 and HDR2, I assume for the wavetable add-on?

QL8X12B-XPL68C Field-Programmable Gate Array, 96 Cell, 100 Pin, Plastic, QFP

Does this mean that the 32 Voice Wavetable is integrated within the QuickLogic FPGA?
Is the 3D Sound Option header mounted?

I/O Port
      The SoundPiper may occupy one of two different I/O port ranges 
         <Port 240>, Port 220, Disabled 

Interrupt Level
   The SoundPiper may occupy one of four different Interrupt levels 
     <Level  5>,  Level  7, Level 10, Level  9, Disabled 

DMA Arbitration Level
   The SoundPiper may occupy one of three different DMA Arbitration levels. 
    <Level  1>, Level  0, Level  3, Disabled 

Joystick Enable
    The SoundPiper has an joystick interface available 
     <Enabled - Port 200-201>, Disabled 

Joystick Wait States  [16/32 only]
   Wait-State generator permits some software that use the joystick to work better on a PS/2.
     <2 Wait States>, 3 Wait States, 1 Wait State, 0 Wait States 

ADLIB/OPL-3 Port Enable  [16/32 only]
   An ADLIB/OPL-3 compatible interface is typically used as the MIDI Synthesizer. Disabling this port may cause your MIDI playback under Windows to stop functioning. 
      <Enabled - Port 388-38B>, Disabled 

MPU401 Port Enable  [16/32 only]
   An MPU-401 compatible interface is typically used to communicate with an External MIDI device or the Internal Wave Table daughter card on a SoundPiper 32. 
      <Enabled - Port 330-33F>, Disabled
