The manual is a good starting point, but I found out much more by running various tests on the real machine, and examining the output in a sound editor, as part of the emulator development. The full algorithm of how I assume the TED sound generators work is in TED7360::calculateSoundOutput() (http://plus4emu.svn.sourceforge.net/viewvc/plus4emu/plus4emu/src/ted_snd.cpp?view=markup), which runs a single 221681 Hz cycle of sound emulation (note the various hacks for emulating the oddities of setting the frequency to $3FE).
