There have certainly been many tweaks, enhancements, bug-fixes, etc. but the core IEEE Math routines created in Saturn assembler form the basis of the actual math routines used for the next 30 years. One of the original developers has commented that it's likely many of those routines survive untouched all the way through the 50g. I was pretty sure that the work done on the 71B and the 15C was ported in newer versions (even in the Prime? I read somewhere that they port the code slowly). As you correctly identified, though, my point was about a basic system with such libraries. It would have been superior to the current ti/casio basic versions in my opinion. Wikis are great, Contribute :) |
