Digitalker 54104 IC

I know the SP0256-AL2 (it is a zero not an ?ooo?). That chip is a phoneme generator and it was described in a BYTE issue. It has (IIRC) 6 ?data? inputs to select one of the 64 stored phonemes, and a strobe signal. Depending on the suffix (here ?-AL2?) it contains certain phonemes and can co-operate with external premanufactured Speech ROMs. You can google for more info on the SP0256-AL2. The ?-AL2? was the generic phoneme chip, I used it in my StarShip back In theearly ?90-ties. *very* robotic speech ? Note that the chips needs an external Xtal of somewhat odd frequency, but I think it will work with an Xtal of (again IIRC) 3.2 MHz.

Would probably be fun to hook it up to an Arduino and see what it has to say. :-) bill
