For example, it says that #34133h is the address of a string called tokCopyright which contains "Copyright HP xxxx". But it doesn't, and executing PTR 34133 crashes. Same for 340CB (tokVersion) "Version HP49-B...".

These were valid in the 49G but are not valid in the 50g. Is there a document that lists the useful "Unsupported But Stable" entry points for the 50g?

Yikes! Good question. I just did some sleuthing and found that my currently-installed extable matches bytes and cksum with the "extable2.lib" version from emacs211a, and it definitely includes those two tokens as well.

While I was looking at this, I also noticed that Jazz 50g has a rather large extable replacement as well. Perhaps if Han sees this he can provide some insight as to the symbol source for that one, but a quick check showed that it also has those two tokens. So I'm thinking that most of the updated ones are probably pulling a similar list to Carsten's database, which has both of those. As well as the newer ZINTs and FPTRs, and... lots of other things it appears.

That's a long way to say "I don't know of one" . But maybe we can shake enough trees to see what kind of fruit will fall.
