Does this Mindscape Music Board reproduction qualify?
The layout is reportedly still untested, though.

It certainly does, but in my opinion this needs more than a reproduction, needs also a tweak so it isn't dependant on the system bus clock. It needs its own internal oscillator to keep things real even if you put it on something faster than an IBM PC. It would be nice if one could set the card range, at least on one of the chips to the Covox Sound Master, as at least it could play stuff intended for it.

On the software side, an AIL2, AIL/32, MSS3 music driver(s) for the Mindscape Music Board would be very cool, as it has dual chips so 6 voice support.

In the meantime, I have built a card – two, actually – and can report that I have been able to come up with a near-trivial modification that gives the card its own oscillator and is completely solder-less, provided that the clock divider flip-flop is socketed.
It consists of a wire jumper bridging positions 6 and 8 of the socket and a suitable CMOS oscillator (e.g. 2.4576 MHz) that is then simply plugged in.
You can see the result here: Re: Mindscape Music Board Replica

The base address of a Mindscape Music Board can (theoretically) be configured between 000h and 3fch in increments of four.

Great job!

Thx!

Thanks for maintaining that list! I noticed the CMSLPT is listed in the Soundblaster section, but belongs in the Game blaster/CMS section instead.

Furthermore, I don't like the term "audiophile-grade capacitors" used in your description of the MK8330. The original post calls them "audio-grade" (at least now), which still is a unsharp term, yet it has some meaning attached to it ("the vendor considers it suitable for use in the audio signal path"). Audiophile-grade sounds just like a pure bullshit marketing term to me. I'd recommend to remove "phile" to stay with the term endorsed by keropi.

The Picovox can be added to this list as well.

It's the same idea as the PicoGUS and the PicoMEM, but in the form of a parallel port device.

It's a parallel port sound device built around a Raspberry Pi Pico 2 (RP2350).

It is being developed by @jansakos as a university thesis project.

It can currently emulate the Covox Speech Thing, the Disney Sound Source (albeit not yet perfectly), the FTL Sound Adapter, the Stereo-on-1, and the OPL2LPT. Emulation of the TNDLPT and CMSLPT is currently a work in progress.

Additional features, including non-sound functionality such as printer emulation (storing "printed" pages as PDF files on external storage) is under consideration as well.

Bog standard high ESR caps... apparently even low end shit is "too good" for audio now though.
