And the specifications changed a bit since that posting, well primarily the number of programming steps got massively increased -- some in RAM and many many more in flash -- mostly thanks to Marcus who implemented all this. Then we added double precision, some more registers, many more programming functions, stopwatch, printing and more. For longer than I can remember, I'd had been working on some mega-super-four-banger-scientific firmware, several parts of which made it into the 34S, before I contacted Walter about a collaborative project Finally, this was the 34s not the 34S. We uppercased the name later. The bottom line is writing quality calculator firmware in your spare time takes years. As a full time job, I expect it still takes quite a while to get things right. - Pauli |
