Since some people already managed to convert the SPC700 Audio Processing Unit (APU) to a standalone device (SPC player),
I wonder if it would be feasible to create a PC interface for it, be it ISA (or ISA+PCI/PCIe) or serial/parallel.
Or if it would be possible to interface one of the compatible audio sub-systems.
(Things like FC-Twin&Retro Duo also contained S-NES logic, sometimes with additional main RAM, even.)
This thread is merely intended as a brainstorming, I have no concrete plans to assemble such a thing yet. 😉
The idea in itself would be interesting, at least, I believe. 😀
For those of you who haven't had so much experience with the SNES platform,
the SPC700 basically was a dedicated audio computer/audio coprocessor thing.
In some ways or another, it is related to the wavetable synthesis / Amiga MOD format.
Some people also would describe it it as an intelligent RAMpler (as opposed to an ROMpler), I suppose.
That being said, it's not so much about creating an 1:1 replica of the original, but rather about playing around with ideas.
Maybe creating a hardware-based SPC player, also, that would work differently internally -or use existing off-the-shelf chips-,
but had the same capabilites of the APU ?
Why ? Good point, the main idea would be to be able to play/compose existing SPC music on a PC (-> think of Adlib Tracker, ImpulseTracker)
or to create new homebrew games that could utilize that sound board. Or something completely else. 😅
I just came up with the idea when I thought about all the different retro sound cards that we already have got now.
