To weirdocollector:
I have the DivGMX slotted into ZXBus 1 on the EVO. The card itself is actually shorter than the full length of the Evo's ZXBus slot, but it fits nicely. I have the card shifted towards the back of the Evo (closer to the output sockets) in the ZX Bus, orientated with the video socket and sound socket of the card pointing towards the back end. I didn't find any info on how to install it, so looked up the ZX Bus image on a video of the card installed on a ZX Phoenix and made an educated guess!!...
As for how to use it, it doesn't interface directly with the Basic user interface at this point (I'm not using it as a NEoGS right now, but as a General Sound card combined with the SAA and TurboSound card)... I think the user interface in the basic setup of the Evo only allows you to reset the NeoGS card anyway, so you wouldn't be relying on that for playing anything anyway (Perhaps the TS-Lab configuration has more options for NeoGS cards, which you might be thinking of?).
To use the card, I'm running a range of different programs... I am running it through demos, games, and a few dedicated editors and players - there is a lot out there on the internet, if you look up General sound...
https://vtrd.in/ has some interesting software. Since I am not a programmer, I am relying on available editors and music players for the Evo to interface with the card (they usually find it without any configuration, although if used as a SoundDrive, Iv some times been asked which port its on, but it depends on the software your running).
It this point, I have speakers plugged directly into the card, and the main Evo sound output plugged into my monitor, so effectively have two sound output systems. The main Evo outputs the AY, and Beeper (when it works), while the General sound, SAA and other sound engines output the card directly...
I'm still finding out what works and what does not at this stage, but overall, Im quite satisfied...
