[net.micro.mac] Mac in Stereo?

keashly@winston.UUCP (Lance Keashly) (08/07/86)

I was just peeking in Inside Mac and saw the disk speed sound interface
diagram. According to what I've heard the new 800k drives have their own
speed adjustments so they don't need the mac to regulate it. Well the speed
regulation is part of the sound generation, they are a stream of 16bit values
8 bits for disk speed 8 bits for sound.

So my question is what is involved in making a stereo mac? Am I wrong in
some my observations? I really don't know hardware but it seems like
everything you need is there.

When one of the Apple people was speaking here, he said something to the
effect that at one time the Mac was going to have stereo sound; however,
when they switched from the 5.25" Twiggy drives to the 3.5" Sony drives,
they needed a speed control -- hence the loss of the second channel.  I'd
be surprised to see a stereo MacPlus anytime soon -- the current MacPlus
does have the ability to use the old 400K external drives, and Apple would
have to take that away to get the second channel.  Of course, once the open
Mac appears, a number of multi-channel music cards may come out (remember
all the ones that appeared for the Apple ][?)
