Yes, DM42 is smaller. And with upcoming FW update it will be very small RPN graphic calculator!
Before we get done for false advertising, please be aware that having a fully usable high resolution screen does not make a graphing calculator.

The DM42 has no mathematical functions beyond those of the HP-42S but it does have a much nicer screen :)

As long as you can set and reset any points on an all-points addressable screen, it is a graphing calculator. You can use the built-in functions (sin, cos, tan, etc.) and scale them to fit the screen yourself. It's still considered a graphing calculator.

Never heard of a forum being sued for false advertising. IANAL though.

Was the HP-42S marketed as a graphing calculator? No. HP describe it as the HP-42S "RPN Scientific Caclulator". Yet It has the features you describe...

I would argue that a graphing calculator should have instructions built in to allow plotting, tracing and analysing functions. The HP-42S (and DM42) do not have this.

Just my 2p worth...

how do dplot_original and dplot_thomas work? I tried loading dplot_thomas and got to the point of entering a function, but got a little stumped.

nevermind. "google that shit" and got http://www.hpmuseum.org/cgi-sys/cgiwrap ... ead=222773

It's kinda cool that DM42 displays the function in one part of the screen and the stack in another part of the screen on the current firmware.

The 42S didn't have a big enough screen to be useful, I guess. HP was very conservative. I've seen calculators with less graphics functionality than the 42S still marketed as graphics calculators (The Casio 6300G/Durabrand/LeWorld calculators come to mind). There could be a difference in semantics between graphics calculators and graphing calculators. Mea culpa.

Wikipedia equates graphing calculator with graphics calculator.

From: https://en.wikipedia.org/wiki/Graphing_calculator:

"A graphing calculator (also graphics / graphic calculator) is a handheld computer that is capable of plotting graphs, solving simultaneous equations, and performing other tasks with variables. Most popular graphing calculators are also programmable, allowing the user to create customized programs, typically for scientific/engineering and education applications. Because they have large displays, graphing calculators also typically display several lines of text and calculations at the same time."

It seems to me that the origianal HP-42S meets all the criteria.

When I hear the words "graphing calculator," I think of machines where you can enter a function, and some limits on the various parameters, and then said machine shows a graph on the screen... and where those machines can do that, without the user having to write, or load, any programs in addition to the function to be plotted.

HP RPL calculators: graphing
HP-42S: not graphing

The DM42 hardware may be capable of being a graphing calculator, but with Free42-based firmware, it isn't a graphing calculator.

I'm a bit surprised this discussion is even taking place. I mean, would anyone consider the HP-41C to be a financial calculator, just because it is possible to load programs into it that perform financial calculations?

yes, everything is in Github :)

Binary arithmetic isn't desirable for a calculator :(
