CHIP for the HP-28S! Yes, that is what I am currently working at. But I need to know these addresses (from ML): - Allocate string - Check 1 argument on stack - Save & restore RPL-registers - Push short integer on stack - How to access the speaker Now, I could of course find these myself, but that would take som time. And I'm pretty sure there is some 28-gurus out there that have this all written down. So please email me if you know some of these addresses. Thank you! Erik Bryntse erikmb@cd.chalmers.se

A similar thing happened to me after loading the Strange library, except I was using another program, James Donnelly's FCAT, when the calculator died. However, I was able to restore it from a recent ARCHIVE without any problems. >When I perform step 2, rather then getting 'Backup HOMEDIR' on the >stack, I get a string, which appears as "HPHP48-Ab+`<xxHOM... >(where < is the angle sign, and x's are block chars.) >I can't edit this, because the string contains null chars.

I believe ARCHIVE always uses binary file transfer. If C-Kermit was not in binary, then the backup would not have been saved correctly. I don't know of any way to recover from this, but then I haven't tried real hard. >Please reply soon!
