Hi,

Looking for old eighties speech synthesizers / speech processors and their ROMs and some other stuff.
Digitalker ROM MM52116SHRL (other letters added to MM52116 are not the right chip) [National Semiconductor]
...
Hi,

I know this is an older post, but I just ran across it.
Are you interested in a set of these (never been used) Digitalker IC's?

Hi Ray,

That is a very nice set, or actually they are two! Especially the SSR5 and 6 are hard to find. From the Digitalker persepective, I got the Digitalker itself (MM54104) and the (contents of) the SSR1/2/5/6. The SSR3 and 4 and the MM52116SHR/L are supposed to exist as well, but I have never not even seen a trace of them. And then there is the DTSW500 Digitalker CP/M software, where based on a vocab on 8" floppies (?), you could create the contents of your own (EP)ROM. It must have existed, it is on some old 8" disks on some attic somewhere, but I wonder if I'll ever find it ;-)

But I'm sure there is someone reading this thread that would love to become the new owner of these sets!

Thanks for posting and stay healthy!

George

Hi Eric,

Thanks for your post. Well, you saw my list in the initial post,let's keep the communication open to everyone, there might be more people interested: so, what have you got available?

Cheers,

George

Hi rsjsouza,
I cannot PM yet. Please supply additional contact info.
Your answers: 8.30 & YES. Thanks.
Hi @klclab , if those DIGITALKER ICs haven't found a home yet, I would gladly put them to good use and share my findings. I created an account here on AAC to reply to this thread, so I can't direct message yet either. My email is my username here on AAC at GMAIL dotcom.

BTW - @georgedb I see your WANTED posts everywhere. It's nice to see someone else so fascinated by these speech chips. :) I would love to pick your brain and exchange a few phonemes with you!

Sorry to say they have found a home already. Glad there was some interest in these!

Feel free to pick ;-) My time is extremely limited these days though: bought a house which requires quite a bit of TLC. This will take another year, hopefully then time again for some electronics...

Hello,

Also looking for SSR5/SSR6, MM52116 (Ans SSR3/SSR4 ...) files dumps to finalize my DIGITALKER TEST BOARD.

Actually V1.0 with SSR1/SSR2 and JAMECO JE-520 Roms works fine, V1.1 is under development to accept 16 (8k * 2) voices roms sets ! (Actually design is for 4 sets of (8k * 2) voices roms sets).

Here it is :

Start / stop and voice set selection done by Arduino.

All design code made by me.

François

PS : I can dump all voices rom, so if any of you want back-up let me know !

@Flip78 The Digitalker Test Board looks amazing. It would be great to be able to load all the ROMs on one board. Is there any way to have the Arduino (or other microcontrollers) drive the speech data for the MM54104?

Understandably so. Well, these 80's vintage chips are 30+ years old now, what's another year or two? I'm doing my slow but steady self learning of electronics coming from a software engineer's perspective trying to get into hardware hacking. I haven't picked up a soldering iron since my EE labs in college 20 years ago! So, I'll be around... :)

Sounds good; have fun! So much info these days, but it takes a lot of time. Rather than soldering, I prefer a breadboard ;-)

Probably yes, the new board will be available, with big memory i can now store all voice proms known (by me ...)
