Has anyone managed to get a rom dump of the 83 or the 86? The 83 especially. If so, we could find the source of all the 83 functions, using the addresses in ti83asm.inc, and do a simple search for that in the ROM of the 82. After we find out where they are, it would be simple to make an 83->82 conversion header. For the functions we can't find, just include the source in the header.
