RE: 20b or 30b for WP34s
(11-17-2014 06:43 PM)Marcus von Cube Wrote: There must be a hidden feature in both machines that allows HP's original firmware to detect the hardware it is running on. The enhanced features of the 30b aren't available on the 20b even if you load the 30b flash image on it. On the HP50G, HP49G+, HP49G, and HP48GII, there is an opcode that behaves differently on each machine with allows assembly software to detect the type of machine. Perhaps something similar exists for these calculators? Graph 3D | QPI | SolveSys |
