I wonder if we'll see it in other (future?) non-68030/020 Macs as well. Maybe there is something about running at 8MHz but i really doubt that would be a prob. My best guess is that all the new Apple CPUs (excluding the low-end, likely) will have it, since it improves greatly an area of Macing that Apple seems to be pusing real hard now, Desktop Multi-Media... Anyone have gutty, low end details on this chip? I know it offloads considerable processing that Mac SE and down struggle with. Robert Minich minich@a.cs.okstate.edu OKlahoma State U. "Followups to comp.sys.mac.hardware" seems to be in order here. Have a nice day. :-|

Wait, the Mac II I had in 1987 had a stereo sound chip. I was using SoundEdit and my stereo for some neat effects as early as the summer of 1988. -- Mark Wilkins wilkins@jarthur.claremont.edu

Yes, the Mac Portable, Mac SE/30, and all the Mac II machines use the ASC (Apple Sound Chip) and two Sony sound chips (analog/amplifiers). >Anyone have gutty, low >end details on this chip?

For more detailed info on the sound circuitry, check out the "Macintosh Family Hardware Reference" published by Adison-Wesley. If you want to program with sound, though, I'd suggest getting a hold of the soundmanager documentation. It's available for anonymous ftp on apple.com, in the directory pub/dts/mac/docs/soundmgr.hqx. While you're there, you might want to get tech note 168 (on playing sounds in hypercard) in pub/dts/mac/tn/tn.151.200/tn-168.hqx. noah ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ noah@apple.com Mac IIci Hardware Design Team ...!{sun,decwrl}!apple!noah Apple Computer, Inc.

Unfortunately none of these has any information on how the actual chip works. All would be fine, if the sound manager allowed full use of the ASC, but it doesn't. I ordered the Macintosh Family Hardware Reference just to see how to use the ASC, but all it contains is what the ASC can do and not how. _._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._._ | Juri Munkki jmunkki@hut.fi jmunkki@fingate.bitnet I Want Ne | | Helsinki University of Technology Computing Centre My Own XT | ^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^
