Why isn the HP49G expandable?
The HP49G has a total of 2.5MB of memory (512KB RAM and 2048KB flash ROM). Because none of this is covered, a new bank-switching algorithm had to be created. Also, the HP48’s memory management is VERY slow, especially with memory cards installed, so memory management had to be rewritten, resulting in a 10 times speed increase. The new memory architecture is very open and very easy to program, but the current version lacks the possibility of an expansion port. Perhaps this could be added in the future, but only time will tell. In addition, the HP49G doesn’t have an X in its model name (like the HP48GX and HP48SX) so expandability should not be expected. HP has not announced an HP49GX.
