WP 34S Overlay Available For V3



#3

I just noticed that Eric has updated his overlay with the latest graphics for V3.

Looks like I need to buy another 30b.

Because you don't want to remove the overlay from the keyboard of your previous one you have on hand?


#5

Has anyone tried removing an overlay? How did you go? How did you do it?

I removed one of Eric's original matte finish overlays from a 30b. I wanted to replace it with one of the new satin finish ones which I thought looked much nicer. My intention was to attempt to remove it more or less intact so I could hopefully re-install it on a 20b that I had kicking around. Removal of the key-plane sticker was not difficult, I just lifted a corner and started pulling. Any hope of re-use was quickly dashed, as the very thin sections between the keys stretched and broke. Once I got the whole overlay off, there were a few places where the adhesive was left behind. This was easily removed just by rubbing with a soft cloth. To remove the key labels, I lifted a corner with a knife blade and pulled them off. Quite a bit of adhesive was left on many keys. Since the keys are not nearly as smooth as the keyboard plane, I did not think I would be able to simply rub the adhesive off. Rather than risk creating a gooey mess trying to somehow clean the keys, I decided to just leave it. I hoped that leaving the adhesive residue on the keys would be OK, since I was going to apply new labels anyway, so there would just be more adhesive in some spots. I then installed the new satin finish overlay and key labels. Over the next few days, various corners of various key labels kept popping up. I would rub them down, then later another would do the same. I eventually rubbed all of the key labels fairly aggressively with some smooth, round-ended tool, which seemed to adhere them. If I had it to do over again (which it appears that I will), I would find a way to clean any adhesive residue off of the keys.

Need a picture! Especially with the obligatory VERS screen.


#8

It basically looks just like the first picture below, except it is a version 2 layout. I believe that the second picture below is the original matte finish version (on a 20b), the type of which I removed and replaced.

#9

Very nice - may I use you 30b picture on the wikipedia page?


#10

The pictures are Eric Rechlin's, so I cannot grant permission.


#11

D'oh - missed that part - Eric?

#12

I have high quality v2 pictures on my FlickR account with Creative Commons licence that you can use. Alas, no VERS screen. I will add v2 picture with a VERS screen and v3 pictures as soon as I receive the new overlays.

Thanks for your warning concerning removing the adhesive sticking to the keys. I will certainly take this to heart when "updating" the overlay.
FWIW, I installed the matte overlay to begin with, but on a few keys on top, the lower corner keeps popping up ever so slightly. I would recommend not only thoroughly removing any adhesive residue from the old overlay, but also cleaning (perhaps with alcohol) every key before installing the new overlay to remove any fingerprint residue. You also *really* need a pair of tweezers to apply the individual key overlays neatly. Rub firmly around the edges after applying.
That being said, I have nothing but praise for Eric's overlays quality wise.

I'm a collector at heart. The V3 upgrade represents substantially more than just moving around a few keyboard labels. I would no more replace the firmware and overlay on my WP 34S V2 than I would replace the ROM on my "all bugs" HP 41C. Ten years from now, I will be proud to display and make occasional use of the complete series of all of the WP 34S variants that were ever produced.

(I predict at least five distinct versions before each member of the PWM trinity is institutionalized by the authorities of their home countries.)

The v3 version will be significantly better than v2 in so many ways. At the rate I'm reclaiming flash space by converting functions to keystroke programs, it will have substantially *more* flash for user code than even v2 *without* matrix support.

Seriously, forget v2 it is little more than a testing of the waters now :-)

2202 and counting -- you'll never get them all :-) If you do I'll be very impressed. Even so, all firmware revisions and changes will survive on sourceforge forever so they aren't exactly collectable.

Sadly, I don't :-(

Well I hope your last sentence will not be true if we replace "flash" by "bugs"! ;-)

You certainly know the saying "never change a running system", and you've developed all those builtin-functions over a long time and they have been tested thoroughly. Now you're rewriting lots of them as XROM code and so chances are not so small that many new bugs will be introduced (just remember your previous MIN/MAX attempt ;-)).

#17

We'll fix the bugs as they are found. I've also found a new bug which I've fixed -- to be honest, I don't think that a lot of the built in functions have been stressed all that much by anyone yet.

At least this time I'm making an attempt to verify the functions before I commit them -- I didn't do that with min & max with bad consequences :-(

We should all still run the ENIAC then? BTW, you can stick to an older version of the firmware or use another calculator.

The WP34s is not a life-critical system as far as I know ;-)


#19

Well, ENIAC would just run for some hours before needing changes of some of its electronic tubes, because they aged and failed frequently. So it would not keep its "running system" status for long.

Ah, but the overlays themselves might be, assuming Eric didn't vastly overestimate demand.

#21

Note that Amazon was selling a 30b for US$19.- just recently... now I just ordered a set of overlay (gosh I hope I ordered the v3 version...), Gene is sending me a cable, I should soon be the proud owner of a WP34S !

Question: has any one tried using an AVRISP Mk II instead? will give it a try...

This tool is for programming the AVR line of micro-controllers, not the ARM based chips.
