Ah, the good old days, when smart programming could make your hardware
do stuff it was not supposed to do.

I remember using the SpeakJet chip (http://www.speakjet.com/) for speech
generation when I really wanted the
tinny robot sound. I believe it is actually a pre-programmed PIC.

Onderwerp: [PIC] Really old pic chips

I knew microchip had been a maker of chips for a long time but I didn't=20
realize how long until today. I once  owned a tandy color computer in=20
the 80's and bought the speech and sound pack for it. Today I was=20
thinking about the system and the sound pack and decided to dig around=20
for info about that pack . The pack expanded the system to do text to=20
speech and also extra audio using the ay series of sound chips.  To my=20
surprise I found that the micro in that pack and the sound allophone=20
chip were made by microchip. The part numbers were :
SP0256B  - Narrator speech processor - text to speech algorithm=20
included, 3.12Mhz
PIC7040 - 4kb rom, 2k ram, 1.78Mhz

The site here has the datasheets:

Anyone know why microchip didn't continue to support text to speech as I

don't really see any of their current products supporting that area. I=20
just found it interesting that all the time growing up I was using a pic

chip and never knew it . I would really love it if microchip produced a=20
newer version of the chip, I could see lots of potential for such a=20
chip.  That or just a general sound chip like the AY-3 series yamaha did

would be useful  for function generators and sound effects.
