They're not completely gone, but they're hard to find. This book describes an early version of Dylan that was very close to Ralph: https://www.amazon.com/Dylan-Object-Oriented-Dynamic-Language/dp/B000KGC0HA It wasn't exactly the same. Ralph had some extensions that weren't part of the language described in the book. For example, it had a class for representing blocks of memory allocated outside the Dylan heap (that is, "foreign" memory). It used to be possible to find a copy of the book online, but I didn't turn up anything with a quick search. I think Bauhaus sources still exist somewhere, but I don't know how you'd get them. I asked Apple about releasing them some years ago and they ignored the question. A few years later I asked whether they were still in Apple's software library, and the person I asked--who, I would have thought, should know about it--didn't seem to have any idea what I was talking about. Maybe they ditched the software library. Once upon a time there were videos of some of the demos that various folks did of pre-release Newton features. Maybe some of those still exist somewhere; I don't know.
