A Serious Scientific Instrument Revisited



#6

Hi all,

After shifting keys around some time, I found a solution well within the keyboard of the coming 35S:

You'll find all the scientific functions in 2 lines of keys top left. Around ENTER, there is the classic layout of register and stack operations. On the right, below of the cursors, you find the keys for programming. The shifted keys 4 through 9 are for mode and base setting. Combined with the right arrow (unshifted GTO), they perform conversions.

This proposal allows for reusing at least the 35S housing and keys for some further development.

Oh, and for those members of this forum suffering from an allergy to diamonds, a slight modification may be more favourable:

However, this would leave the 35S's keyboard of course.

Both proposals would work with the poor old 2-line display of the 33S, too, but it would be a pity IMHO.

OK, now it's your turn again :-) but remember, if you want different functions, please tell me what shall be omitted for them.

Looks good -- I'll take two.

I gotta say, the (improved) 33s display has very nice contrast, and is very legible. Better, I think, than the graphical dot-matrix display as mocked up on your proposal.

So, I'd be happy either way.

Quite apart from display, alpha functionality, and the functions' arrangement, I do hope H-P will deign to pay attention to your suggestions re: keyboard colors and legend placement -- your images are very legible, indeed!

I think the two-line display looks better, but I could live with four.

Yes Yes!!
A very nice layout, Walter.

Another proposed HP with the Enter key in the proper place.

I love it!

HP, are you looking at(and learning from) these posts? (I hope so).


Best regards, Hal
