Over on Sergey's AY Chip page you can find the latest release (v3.6, fact-fans) of the "AY Composer's List" by Alone Coder. It's a list of all the people known to be working on the great AY chip. Of course it may not be complete which is where we come in. Sergey will be keeping the list up-to-date, so if you spot any additions or corrections, contact him for inclusion in the next release.
