SP0256-017 says some numbers and plays little melodies

I just received an SP0256-017 purchased on Ebay as the one on this picture from Flickr.

This version of the SP0256 was designed for talking clocks. I work with the help of a dedicated EPROM which hold the code for the numbers (without the EPROM, it can say the numbers from 0 to 10 but then it hangs). This version cannot says the allophones as it’s bigger brother the SP0256-AL2 variant

I found the data sheet here but the quality of the scan is quite poor. I used the schematics from the SP0256 to understand what to do.

The sound are quite funny and I couldn’t resist posting a little message just to let you ear this chip.

Oh	Eighteen
One	Nineteen
Two	Twenty
Three	Thirty
Four	Forty
Five	Fifty
Six	It is
Seven	A.M.
Eight	P.M.
Nine	Hour
Ten	Minute
Eleven	Hundred Hour
Twelve	Good Morning
Thirteen	Attention Please
Fourteen	Please Hurry
Fifteen	Melody A
Sixteen	Melody B
Seventeen	Melody C

I just coded a loop to ear this table.

    PORTD = p;
    // Set !ADL=0 for 2usec to tell the chip to read
    digitalWrite(ALD, LOW);
    delayMicroseconds(2);
    digitalWrite(ALD, HIGH);
   // Wait for SBYto comme to 1 (standby) to indicate chip is done speaking
    while (digitalRead(SBY) == 0);
    
    delay(100);
    }
    
   delay(2000); // delay 2 sec between test
}
