I'm trying to control access to a videodisc player (Pioneer 6000) from within a relational database application, written in 4th Dimension for the Mac. Before I set out to do it myself, has anybody out there either 1) written the 4D external interface routines already (in C preferably), 2) adapted the existing Hypercard XCMD (written in Pascal, I believe) to work under 4D, or 3) written the interface routines within 4D, using the serial port communications primitives? Code, comments, and suggestions are much appreciated. Thanks, Adam Galper Stanford University

I didn't have more than a cursory look at it, but it would seem to fill the bill. The developers were two guys from ACIUS (Todd Carper and A.J. Jennings, I think), and it will eventually be sold for $200, but someone at the company may be willing to discuss how this can be done in a generic way. Since the original sender is from Stanford, he may be able to talk with one of the developers in person in Cupertino.

I haven't implmented every feature that the player supports, only those my project has required at this point in time. Still, I'd be happy to discuss this with you. Also, I am in the process of adapting some Hypercard XCMDs -- not for laserdisc control, but for controlling a RasterOps digitizing card -- for use in 4D. I'll be using a program called XLink to do this. Again, I'd be happy to discuss it, since this would directly apply to adapting XCMDs that control laserdisc players.
