1983 - 1984, I am wondering if this might be it. If so it has some
programmable filters (low pass, high pass, band pass) on the PSG
outputs. It only has mono outputs and the Apple interface bus timing
for the AY3-8910 was a little flakey.

I had my eye on it for almost a week. An interesting combo
of 9918 sprite card and AY-3-8910 sound chip.
Also interesting that they didn't find a way to route the video
output on the PC board. ;-)
I missed the run-up to this. A friend of mine who I have not seen in
years designed a board called the "Sprite-n-Stereo" card. Is that what
you have? If so, quite a rarity.
It's pretty close! There is one AY-3-8910, so it's a "Sprite-n-Mono"
card. ;-) I note from the picture, though, that there's some 2-channel
funny business at the audio end, so maybe it _is_ stereo...that would
mean that the video is available only at the RF modulator connector.
I've never seen this combo before, and am looking forward to seeing
how the 9918A and the '8910 are interfaced, since there's nothing
but "glue" logic on the card.
