FACTOR   (details) 48 ENG   7KB/3KB
This is a program that can factor large integers (up to 63 bits, or 18 digits) on the 48. It's very fast and has a separate prime testing routine.

Factor 1.1   (details) 49/50 ENG   8KB/2KB
This library contains a high speed factoring program, with verbose messages. It is about twice as fast as the built-in routines, and much more than that for numbers of 16-38 digits.

HLDRAW 2.6   (details) 49/50 ENG   15KB/3KB
ScreenshotHLDRAW does what WIREFRAME should have done: fast, true photographic, hidden line removed 3D plotting. It is possible to easily adjust the viewpoint so that you can rotate the graph.
By Jurjen N.E. Bos. 2001/05/21

HLDRAW 2.61   (details) 49/50 ENG   17KB/4KB
ScreenshotEquivalent to WIREFRAME plot, but with hidden line removal and shading of "underside" of 3D graph. For the 49g+ and 50g (ROM 2.15) only. The previous version only worked on older ROM revisions (older 49G ROMs only?). Modified to work with most current ROM. Source code has been updated as well (for on-calc compiling only).

IA2B2   (details) 48 ENG   2KB/1KB
Small User RPL program that extends the functionality of PA2B2 to any number of less than 25 digits. (It could be extended to any number, but it will be a lot slower.) Its result is a list, which will be empty if there is no way to write the number as a sum of two squares, which is often the case.

Nosy+ 4.1   (details) 49/50 ENG   46KB/8KB
ScreenshotNosy allows you to interactively see into the ROM. It allows to quickly "surf" through a routine and peeks into flash pages. This modified version supports the larger screen of the 49g+ and 50g.
