I've got the STB SoundRage 32 Pro "USA201 rev A".
It has 512KB RAM (SOJ, no SIMM slots) and no TEA6330T chip.
I found a bit of info at "STB SoundRage 32 / 32 3D" at https://www.dosdays.co.uk/topics/Manufacturer … stb_systems.php (typo in FCC-id, site owner notified).
It works with the 2.34 Interwave driver, possibly others.

Is there a way I can dump the current ROM? Is the MX chip near the RAM the one that stores the ROM?
If I overwrite the ROM, it is gone forever, right?
Is it realistic that the ROM is something worth archiving, or do I anyway want to use the latest Compaq Ultrasound one? (From STB Ultrasound 32 Pro (Compaq Interwave sound card) - The comprehensive guide)

Identifiers from the PCB:
STB Systems USA201 rev A, T3512-113A. CD_IN, LINE_IN. InterWave AM78C201KC. Year 1996, week 45. FCC id EKSUSA201. PNP id ADV550a "Interwave STB".

This is a mask rom and the data are the same as the Gus PNP so there is nothing new to discover in it...
It is indeed the MX chip and it cannot be overwritten or deleted.

Thanks, then I'll just overwrite, and possibly modify the "rom" to use the original PCI ID. Or just modify the Windows driver to recognize the Gravis id.
