Steven Litvintchouk @ MITRE posted this in alt.hypertext and I thought it belonged here where perhaps one of the mavens in Apple...say ATG perhaps, or perchance one of the HyperCommando's might comment on this. David -------------------------------*-------------------------------------- At an OOPSLA a couple of years ago, Apple Computer demoed a prototype called "HyperClass". HyperClass was an extension of HyperCard, in that it replaced the "background card" concept with "card classes" and inheritance. That is, if you defined a "card class" to have certain fields and buttons on it, you could then define a "card subclass" which inherited those fields and buttons (and could have new ones of its own defined as well). There was even a browser for card classes. This was written almost entirely in HyperTalk, as I recall. However, I never heard anything more about HyperClass since then. Does anyone know what happened to it? Is Apple still sitting on it, or releasing it as a product, or as PD, or what? Also, has anyone else ever implemented anything comparable in HyperCard, SuperCard, or whatever?

There might be some confusion with the object-oriented software development environment developed at Schlumberger's now defunct Palo Alto Research Center. Eric Schoen, now of their Software Center in Austin, TX was one of the key players. I believe he once told me SUN was considering distributing the system. But I never heard him say anything about Apple. In any case, that HyperClass had absolutely nothing to di with HyperCard as we know it. John
