Well, without bothering to look :-) I believe that the Sam PSU uses the sound version of the modulator (whereas the Spectrum +3 uses the no-sound version and must have some external hack to add the sound on, a bit like in the Currah µSpeech. In fact, the +3 also manages to create a composite video signal without the use of a MC1377P). I don't know what modulator might have been used for the Amstrad. imc
