Hi all, on the subject of the SPO264 series of chips: I have three of these with the number SP0264-021 that I bought a while back on eBay, hoping they'd have the same vocabulary as the SPO256-AL2. Of course, they didn't, and after some testing I decided
they were just empty. Just recently, a seller on eBay said he'd managed to get them working with an arduino, and posted a sample of the vocabulary: http://1010.co.uk/spo264.mp3
I also got them working with my arduino. Most of the rest of the addresses are filled with the same sort of static noise, and every here and there there's something that could be a sound effect/tone.
