So, the only drawback expanding the supported year range up to 2107 would be that users would have to manually increase the date by one day on or after the 2100-03-01 ("2100-02-29") a single time, and only when using the physical 49g+/50g calculator. The problem would not exist in the emulator. (It would be even possible to add code to silently correct the date, but I don't know if it is worth to add perhaps 100 bytes of code to cope with an event occuring only once. A note in the manual might do as well.)
The only question I have is: why bother shifting the scale by 7 years? HP calcs last long, but I don't think they will be around in 2100. I don't expect people to use a FAT filesystem in 2100, they shouldn't be even coding in 2100 (using neural interfaces of some sort to get machines to do what they want).

It was supposed to roll over from 1999 to 2000, there's no reason to suspect it won't, but in any case, this hardware won't be running in 84 years so it's not a problem I need to address now. I'll leave it for my grand-grand-children to fix if they are interested.
