Re: One production calculator and five prototypes Message #4 Posted by Eric Smith on 12 Apr 2012, 2:03 a.m., in response to message #3 by Walter B
The "white one" (DIY3 in 3D-printed case) uses the same 16x2 character display seen in its neighbors to the left and right. The window allows full visibility of the displayable area with some margin.
The -5 is planned to use the same display as the 4X, which is a 2.7" diagonal 400x240 display, well-suited for soft keys.
The intent for the 41-like calculator is to have keys with essentially the same shape, size, and spacing as the HP-41C series (other than the early "tall keys"). The 3D-printed case used an approximation of that.
For a calculator with the Pioneer/20B/30B sort of key layout, would you want keys shaped more like the Pioneer (e.g., 42S), 20b/30b, or 41? We definitely will have constant row spacing, unlike the 20b/30b which have a larger gap between the second and third rows.
