I would also leave these disks at computer stores and computer club. Although it is now known that the synthesizer is (capable of) higher quality than MP3, my means of programming sounds into it in the 1980's never had a reasonable explanation for why it worked at all, (and I now know that it simply didn't!,) and in the 1990's other unique methods were tried while this one was considered to be the worst kind of digital sound ever invented. The disk "apparently" has male female and robotic TTS voices, 2 songs, and a few talking games on it. But it seems to have been proved an accidental illusion, especially since it is known to be inaudible through a telephone line.
In other words, I still have the right to make random noise and call it music."

It uses the same kind of speech synthesis as my "awful" disks from 1985, but the method of programming sounds was reasonable in this case. This project was cancelled without ever being tested by for whom it was being designed, and is in a very early and peculiar state. It calculates arithmetic using it's memory as a virtual blackboard, exactly as a person would do it, but has a precision of 14 digits. It has the voices of two people, which were copied from my other projects, because I had not yet gotten around to making a voice specifically for it. The synthesizer was hastily set to work below telephone quality and below worst-case MP3 sample rates but I don't think it sounds bad in this video, especially compared to the "1985 disks".
