Save for I/O, the HP42S isn't "nearly identical" but vastly superior in every aspect.

Quote:And as Mark noted, caution is advised when comparing any machine favorably with the 41.

The HP-71B runs rings around the HP-41C in every aspect too, I/O included, about an order of magnitude superior.

Hello Valentin, I hope this finds you safe and well.

Regarding the HP-42S, my comments about being nearly identical were with respect to its programming language, the core subject of this thread.

As for the HP-71B, also my favorite of all HP machines, it is undoubtedly better in every way except size, and still the machine I use and continue to explore more than any other. But the above comments were aimed at RPN machines, again the the topic in the thread, though I admit my statement is not so clear on its own.
