[HP35S] Disassembling ROM
Of course it seems difficult to read the ROM (Brouhaha did an amazing work on this in the past) but we now have simulators and I believe the ROM is this file here:
C:\Program Files (x86)\Hewlett-Packard\HP 35s Virtual Calculator\Models\Model.dat

I checked the preliminary SPLB31A datasheet but couldn't figure out where the RESET vector is. We also don't have a clear idea of where the ROM is loaded though $C800 seems to be a good candidate. If anybody has a clue about that...

Did anybody already attempted to disassemble the 35s ROM?

Note: the ROM is actually embedded into the file 35s.sml
