[sdiy] speech synthesizer and TMS 5220

[Peter Blackett]

Hi,
if you do a search on Google on
ti99/4a speech synth Mame

then the first result seems to have sone info about the chip used.
I think it makes sense that Texas Instruments would use one of their own 
chips  for their computer.
( tms5220 ? )
I used to have a copy of the service info for a Ti994a , but I'm not 
sure where I have " filed it " .
regards Peter
