Yeh!. I've got some FM yamaha YM chips around somewhere too..... I think 
they could easily be used in some sort of DIY thingo, only I cant find any 
data sheets on them... Anyone?

Oh and I've also got an AY3-8914 sound chip as made by general instruments 
and I think they were used in early SEGA video games..
I think these could be quite interesting also.. Anyone done anything with 
them or got a spec sheet?

Cheers,
Dan
