Votrax data sheets found

[Guest]

Archived from groups: alt.games.mame (More info?)

I found the Votrax SC-01 speech synthesizer data sheets.
Complete with pinout, block diagrams, phoneme tables with durations, signal
descriptions, timing diagrams and specifications, circuit diagrams and
electrical characteristics. I have full Sweet Talker (Micromint) docs as
well, which used the Votrax.

If no one else has this info, I will PDF it shortly. I still need a chip to
go further. The internal filtering will present the biggest problem with
emulation.

Comments?

pattern that spelled out:

I noticed that (Pin)MAME is way ahead of me here, as someone else
apparently made this information available already. If anyone is still
interested I can still scan and post this info.

I'm not sure but I think they have that sort of thing. I've seen a votrax
datasheet pdf floating around anyway. The tricky part is how they blended
the phonemes together when moving from one to another. That's what made that
chip so great. Iirc Pinmame ignores this, using the pinmame code in mame
will not happen. I don't remember who said they were going to work on it,
Jarek maybe? . But they were planning on going from phoneme to phoneme and
looking at each transition in order to determine the algorithym.

I worked with others coding 6800 assembly to string phonemes together. We
would listen to the results and 'artistically' make changes to which
phonemes we used.

Thanks for the info.

I found this site already has the PDF:
http://www.redcedar.com/sc01.htm

I'll scan mine anyway, because it looks much better.

<SIGH> That brings back the days of trying to reverse-engineer S.A.M.
on my //c. I never quite got there, but I had fun trying.

I was able to do a reasonable job of emulating the SP0256-AL2 and the
CTS256 in software.

See www.speechchips.com and look for the free ChipTalk download.
