NEAT! Is this from your C128 tower? Nice work, funny video! 
I actually have a Speccy speech synth which is not too dis-similar sounding to yours (amazingly).
Thanks! This is actually on a Commodore 64 with JiffyDOS, but otherwise a stock machine. The 128 Tower is not hooked up atm, but it will be hooked up again shortly as I clear some desk space.
Was your Speccy speech synth hardware or software based? SAM was purely software based.
