RE: realtime audio streaming
Isn't that due to the fancy (under-utilized) audio DSP processor? Jobs made a huge point on that, but I don't know if that was ever opened up for development at the time.

Those stations had a huge amount of real-world features but the huge price coupled with insanely fast-moving consumer products of the day made this stuff a hard pill to swallow. Unless you were making millions of dollars a year from these tools, by the time they we implemented and in use, some new things had come along to obsolete them. The early/mid 80's (I was alive but a young child) looked to be a horrid business landscape when it came to computing, speeds doubling every 6 months, computers costing more than new cars, you needed to leverage them and make money fast or you were wasting your money and effort.

RE: realtime audio streaming
I used a Cube for audio processing and music creation before switching back to a Mac. There were a lot of very interesting audio apps that were only released on NeXT.

RE: realtime audio streaming
Wow - this is impressive.

I remember back in the mid-90s I had a Pentium 75 (up to until late 2000), and to be able to play MP3, I had to change the codec settings in Multimedia settings (Win95), and even after that, it would still saturate the CPU.

RE: realtime audio streaming
Sick! I doubt that is even using the DSP to stream - probably just for playback right? I mean, you could do this with something like netcat or network audio sound (https://en.wikipedia.org/wiki/Network_Audio_System).

Absolutely love your setup! Who cares what they cost in the late 80s! Run 'em until they turn back to carbon dust 1000 years from now! Biggrin
