Just for curiosity: what's the "upside down issue"? The overlay looks sufficiently asymmetric, doesn't it?
Upside down, as in turning the whole calculator 180 degrees with the face facing down, facing terra firma, to see how strong the magnetic material clings to the calculator.

Looks promising ...! :)

Agreed. I will have the tabs cut with the next cut/print. Also from the photo, the lines around the buttons could be a bit tighter. Later to judge that though.

What's there for the magnet to cling to? The original DM42 faceplate?
Yes, the original marked steel plate.

Shame. Is it possible to get material with a stronger magnet? Or is the original plate not magnetic enough?

For permanently repurposing DM42, gluing might be an option. Or maybe SM might be interested in embedding magnets or better magnetic material in future hardware versions to support magnetic plates?

It depend how much in a hurry are you. I think it will be gluable.

The next template will have the tabs cut and fitted, as Inautilus proposed. I am not too worried. Trust me, once a template is on the real medium, with real buttons sticking out, we WILL change small things - and probably many small things. That is my experience.

For future, remember, my steps are: first a template that can be easily made, easily fitted, making the DM42 does what it should. Second option is the template SM's Michael referred to last year. Second, once we have a layout that works, we'll go to him. I trust Dani will volunteer to go see him. But it is very important to first make these first templates, fit them, and collectively decide how it should be improved. That needs to be on SM's inventory to sell. He is willing to do that. Then, we make a real calculator. Once the template is proven, we go to Michael and have those steel plates made and real calc's sold.

Edit: Sent too quick.

The first thing is to get the DM42's out there usable. Then perfect the layout over a few months and make a proper calculator.

Progress.

I am packaging the newest simulator, which was planned for earlier today, but Martin pushed a heap of new BITS menu functions which I had to import first, prior to making the new releases available.

I am attaching these, but I have no time now to do the change document and list of changes. That will come later.

Windows simulator
DM42 PGM file 27

Remember to remove the backup.bin file on Windows,
And remember to to a RESET (g[CLR] [RESET]), as a lot of things changed.

The major improvements are:
  • Martin's BITS menu
  • My STATS data plot function (this graphing is in addition to the GRAPH function in X.FN, which awaits RPN formula entry to become useful work).
  • The long discussed SHOW function is now on the SHOW label, replacing the standard SHOW.
  • There is a few additions to the K.PK menu (yes, also long discussed, I took K.PK). There is now a pack for an optional orange Alpha key (orange on the emulator. On the real calculator it is just the silly old Σ+ key, and a pack for an optional blue shift key also on the silly old E+ key.
  • The coloured lines on the keys that change... The white ones are Inautilus's stroke of genius.
  • Nigel's .d bug is killed. It was exactly as I suspected, I did not update the softmenu. I had no time yet for the cursor key UP/DN bug. Later.
  • I am working in close cooperation with Inautilus' layout artwork. It requires back and forth to get everything synchronised.

The U-SHIFT pack is loaded in the picture, and this pack changes the keys according to the colour codes. The packs are macros that run once as required, re-configure the keys, switch to USER and then stops. You can still after that change any assigned key, run a second pack in addition, or add more assigned keys manually.

Edited for grammatical improvement.

Thicker magnetic sheets may cling better. This one is 0,3 mm thick, or then 0,3 mm thin. That does not leave a heap of magnetic mass on the sheet.

For any add-on solution, 0.3 mm is probably the thickest you should go. To fit the little slots, also 0.3 mm is about the thickest you can go. 0.2 mm is probably better for the slots.

On the other hand, I rarely do my calculations in upside down, shaky environments.

So as long as the overlay stays in place during transport (in the leather case), I think I will be fine! :-)

Minor SHOW bug in version 27. To reproduce it, try the following steps:
  • Clear the stack.
  • Enter 2 300 y^x (to get a big integer).
  • Press SHOW (f[.]). (The long integer is displayed in small font - is this intentional?)
  • Press EXIT.
The lower two stack levels are left blank, and the HOME menu is not redrawn.[/list]
There's no problem with SHOWing a real number.
