DECtalk DTC01 and Tandy TRS-80 Model 100 Singing "Xanadu"

My DECtalk DTC01 singing "Xanadu"; the song data is "streamed" over the serial interface, using the file transmission function of the terminal program in the TRS-80 ROM. A simple null modem cable makes the connection between the Tandy and the DTC01.
The DECtalk song data is taken from www.theflameofh... - genius!
