I am planning to add SPDIF, though it's a little fiddly (the easiest way right now seems to be to actually plumb it in via the FPGA), so I've been prototyping to try adding the relevant stuff to try that out (the chip shortage is certainly slowing things down, though). In the mean time I2S is on the board between the CPU and the DAC, though it'd be pretty fiddly to solder (though definitely possible, I've done similar mods for testing/prototyping on other boards). On the DAC3100, pin 5 is DIN, pin 6 is WCLK and pin 7 is BCLK.
Just as an aside, my firmware does also do ATAPI ZIP drive simulation just now, though mostly tested with a Roland sampler as that was the feature request. HDD is also on the list but I've been juggling it with a few other refactors so not quite ready yet.
