I used this on the Atari computers.
The Apple version included a card with an 8 bit DAC on it that sounded pretty good. The Atari 8 bit computers have a primitive Amiga like set of 4 bit DAC channels. SAM used one of those and also sounded pretty good, though not quite as good as the Apple did.
And let's be clear, none of them were great, but speech synth in the 80's was near magic so people largely did not care.
Never used this tool with a C64.
“Come, come, elucidate your thoughts..”
Once I had it ask the local Sherrif what time it was ...at 3AM.
No, was not my phone. I do know the peeps who contributed the phone never saw trouble. And that was after asking him again.
Yeah, I was part evil as a kid. I wish I had audio of the second call. Good grief! He was hot, but some how picked up on it being kids with a toy and gave us a scary, but hilarious earfull!
Others included dialing local James Bond numbers, and there were more than a few, and having SAM outline a brief mission after the classic, "Mr Bond? James Bond?" intro. A couple played along.
A friend had the TI with its speech system and did a few too.
One thing we learned on the TI was how misspelling things could really improve how understandable the voice was.
A girlfriend was named Teresa, as an example. Treeza worked great.
