DB48X |
|
|
|
More of a "hermit crab" (shell squatter crustacean) than a clone of an existing HP calculator, the DB48X is the RPL implementation that must be installed on a SwissMicros DM42 calculator.
An keyboard overlay is required to replace the DM42 key functions with those of the DB48X keys.
This RPL "calculator," the heir to the historic HP-48, should appeal to fans of the RPL (Reverse Polish Lisp) language, despite the "shell"'s price of CHF 249 (the DM42's price in 2025).

A HP calculator emulator (many models...) and a clone project...
But once again apparently without follow-up...

41 CL |
Can the 41CL really be considered a clone?
Or is it not more of a "hardware" upgrade?
This calculator is made from a HP-41C/CV in which the motherboard has been replaced...
The 41CL obtained benefits from larger memory and "turbo" speed thanks to more modern and therefore more efficient components.
The result compares to a super 41CX which could have been called 41XXL...

For the other clones, it seems that other attempts have existed, old discussions in certain forums seem to bear witness to this but nothing seems to have lasted...
I hope that the inventiveness and creativity of fans will allow us to see the birth of programmable calculators other than through emulators on smartphones.
I will then be happy to update this site!
