DAC is U36 under two capacitors?

BTW why some Maui 1.0 cards have and some don't have WaveBlaster connector?
If is one striped-down variant, are all with same waveROM size?
(when Tropez/TBS-2001/TBS-2000/Tropez32 existing with 4MB, 2MB or 1MB ROMs)

I saw in another thread that that is not actually a waveblaster connector, but actually an input so you can hook up the Maui to another sound card's waveblaster header so you can run the Maui as if it were a daughtercard.

Only time I saw a picture of a Maui with the header was when somebody soldered one to try out what it does. I thought it was an abandoned idea and that there was only one revision.

Do you have any docs/info on this? AFAIK the Tropez classic has the same ROM as the Maui, 2MB. Second Tropez classic revision has a pop in the left channel in combination with some mainboards.

Is that genuinely a 16 bit sound card with a Motorola 68k on it? What overkill! Very cool.

I found only this photo by google search:

Thanks a lot for all of the excellent comments!

There's also a special Turtle Beach daughterboard called Rio that can be hooked up to it. See Turtle beach Rio midi daughterboard

The Rio daughterboard was targeted at Turtle Beach Tahiti users IMHO.

Great card with great possibilities its "only " a midi card but there is a wemp96 player for mods in dos Wavefront Extended Module Player v0.96 by Daniel Baum .

In the manulal its says that you can connect this card to a sound card with the 26 pin ribbon cable to replace its synth
In games Its easier to have maui installed with other sound card and plug the maui sound out to a sound in or auxilliary of this other card and make changes in games setup for midi sounds .
You can find info in the internet that:
SECTION 2: Package Changes
--------------------------

2a) Changes to the Card

The first batch of Maui's had the WaveBlaster connector header,
however, subsequent Maui's did not have this connector. The explanation
from Turtle Beach was that Creative Labs changed the WaveBlaster
specifications at the last minute so the WaveBlaster connector was removed.
For those of you who want WaveBlaster daughtercards, look into Turtle
Beach's Rio card.

2b Changes to the Manual (v1.0)

Since the WaveBlaster header is no longer there, the references to
the WaveBlaster connector and "Internal Serial MIDI Interface" are fairly
obsolete. As far as I know, no one has tried to make their own patch cable
to use the WaveBlaster header circuitry on the Maui.
The JP2 Port settings on page 12 to set the Base Address Maui uses is
incorrect. The setting for port 230h is correct, but the setting for port 210h
should show all jumpers closed.

Did anyone try a daughterboard with the Maui's wave blaster header? I did a "mind" experiment, and if you connect a "proper" waveblaster header (like on the Tahiti mentioned in the manual) via an "unpatched" ribbon cable, you are connecting them 1:1. Given they suggested connecting them this way means: the "voltage" pins are in the same place as in a normal waveblaster header (nothing happens if you connect them together), but inputs and outputs are exchanged, since it should work like a waveblaster daughtercard when connected to a card with a "standard" waveblaster header.

I'm aware that daughtercards with a "reversed" or "mirrored" header existed, but I haven't really seen an explanation of what "reversed" means. Was the connector just on the opposite site? Were all pins mirrored? Or only the inputs and outputs?
