Hi @gerpux, thanks for your interest in my modifications of the original board! I leave here the Eagle project and the gerber files, just in case anyone is interested in sending them for manufacturing, or making further improvements. You rock @davidmorom, that's the spirit! Thanks a lot for sharing …

A lot of people leveraged the original design to make improvements and did not share the PCB design. Note the mods where possible thanks to the MUS-1099 design being open. @davidmorom your PCB can be the new MUS board standard, can you consider sharing it? Otherwise it's reinventing the wheel over …

As Wikipedia writes, "The Sound Blaster Pro cards are basically 8-bit ISA cards, they use only the lower 8 data bits of the ISA bus. While at first glance it appears to be a 16-bit ISA card, it does not have 'fingers' for data transfer on the higher "AT" portion of the bus connector. It uses the 16 …

Well, they're 16-bit cards, and the PicoGUS is 8-bit. Come to think of it, that would also prohibit proper AWE emulation. Not sure why the didn't opt for a 16-bit ISA card, perhaps it's the limit to the number of the RP2040's GPIO pins. That's right, it's an 8 bit ISA port but SB Pro for example I …

Not sure if AWE 32/64 support is doable. Perhaps 32, but recall that the "64" was just 32 + the other 32 in the Windows driver, so for DOS games it's useless. I think the feature set of AWE 32 already exceeded that of the GUS, but it supports both wavetable and OPL3, and I don't think a RP2040 is …

If Tandy is emulated, PS/1 should be easy to do. But since there's so little support for the PS/1, I'm not sure what the use would be. Just nostalgia (and adding one more sound card to the supported list, the more the merrier). With regards to usefulness an awesome addition to PicoGUS would be SB …

Hello! Given there's DosBox support, how hard it would be emulating the IBM PS/1 Audio Card in PicoGUS (github.com/polpo/picogus) It already has Tandy emulation. Currently it can emulate: - Gravis Ultrasound (GUS) - the primary focus of PicoGUS, hence the name - Sound Blaster 2.0 / AdLib (OPL2) - …
