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.

Ed # SMECC The one I have in front of me is the SPO256-AL2 (actual chip is labeled SPO256-017) and the package includes an SPR016-117 which is listed as an External Serial Speech ROM. Would probably be fun to hook it up to an Arduino and see what it has to say. :-) bill
