[HP4x] ROM Disassembly

For example, I have the commented source code for the S/SX (version E) and for the G/GX (version M), but have never given it to anybody without permission.

Has HP ever released these ancient documents to the public, or given permission for them to be disseminated? If not, they should, because there are lots of goodies in the comments (and in the commented-out sections of code).

Apologies in advance if this topic has already been discussed.

Emphasis mine. I too hope they'll give permission to disseminate it. On the one hand, I have already learned quite a bit about the ROMs from my own reverse engineering. On the other hand, it would also save a lot of time for those of us who wish to rewrite some of the ROM. Given that rumors are spreading about the discontinuation of the HP50G, and pretty much all the calculators based off of the HP48 series will essentially fall into the "no longer in production" category, one would think they might eventually.

Then again... I did bring up the subject a while back (comp.sys.hp48 topic) and more recently (MoHPC topic). They don't seem to be allowing any new NDAs... so who knows.
