Full Speech Replacement card

[Shift838]

I've been working on a full speech replacement card for the TI based around my redesigned RAVE99 card.  I know it works with original speech ROMs.  But I don't want to kill a speech synthesizer to do this project.  I did find the TMS6100 emulator that was designed by a guy for use with the Acorn computer.  Of course, their computer only has one Speech Rom.  Where the TI needs two with the amount of vocabulary that we have.  

 

My question is I know the TMS6100 can have up to 16 banks assigned to it so that you can expand vocabulary without having to add additional circuitry.  Does anyone know what bank TI decided to give the CD2325A and CD2326A?  Would it be Bank 0 and 1, or what?

All the info you need is on this page in regard to how the speech ROMs worked.

Basically you have a 20bit address bus. 128k of space, with the ROM chips latching 14 of the bits and the remaining bits internally fixed to a 4 bit chip select.

I believe Michael Becker either included with SPVMC or as additional files lots of extra vocabulary.

When I was the US Rep for SNUG, he had me purchase many speak and spell products and was dumping the speech roms.

That's awesome. To get good quality, there would be some translation involved from Speak n Spell modules to 5220.  It would be worth doing, with all the coding tables we have now.  
 

Strangely, I don't have any Speak n Spell modules.  Even with an embarrassing number of TI talking toys (excuse me, Learning Aids). 
 

I do have a chip VM60001, Industrial Vocabulary, and one (unknown) mystery 6100 from Unicorn Electronics.
