Can anyone tell me where I can find the source to XCMDs written by Dan Winkler to control optical disk players? I presume they have been published somewhere, so if you could point me there, I would appreciate it. Ed Seiler (seiler@chrpserv.gsfc.nasa.gov)

By "optical disk players" if you mean videodisc players, you need the HyperTalk Videodisc Toolkit 2.0. If you mean CD-ROM drives (to play audio CD's) then you need a toolkit called something like HyperTalk CD Audio Toolkit. Both of these are available from APDA.

Thanks, but what I am really trying to find is the source for the XCMDs. I think this may exist in some published work, but I'm not sure. I do have a stack titled VideoDisc by Ted Kaehler and Fabrice Florin that includes XCMDs for certain optical disc players, so that they can be controlled from Hypercard, and the documentation refers to Winkler's work. Perhaps someone from Apple knows? Ed Seiler (seiler@chrpserv.gsfc.nasa.gov)

The videodisc toolkit from APDA includes source code in Pascal. If you want to write your own customized routines you might want to try using the much simpler "SendSerial" XCMD to send codes to the player. Jim Taylor Microcomputer Support for Curriculum Brigham Young University taylorj@yvax.byu.edu

There is a source for at least a FEW of the original videodisc XCMDS -- try Phil And Dave's Excellent CD, burrowed someplace in Developers' Services code... In either MPW Pascal or C... If not, I'm sure you can get them somewhere (I have them here on my HD...) A word of advice: Avoid Apple's so-called "VideoDisc Toolkit", it makes a mess of things (too much error checking... bogs down the system FAST...) --

What are the problems with the Apple VideoDisc Toolkit? Of course the faster the better, but I don't think speed is that much of a concern when you are interacting with a videodisc player.
