I can't wait to see that HP-41 replacement CPU board!
04-29-2011, 03:24 PM
indeed! where can we get that 41 replacement board??

Gene, I have visited the site but I don't see how to purchase one or get on a waiting list. Any pricing information, etc. available? Thanks.

I also found the "Tweaking the HP42S" article interesting. Specially in light of the discussion of the WP34S keyboard layout. Although I have to say that I have a BIG problem with putting the X<>Y key on a shifted keyplane (as seems to be suggested by the image). I use X<>Y a lot more frequently than I use RDN and personally would switch those two if I could not have both unshifted.

I have to say that Gene's review can be used as a "getting started" guide - better than the one provided with the actual calculator. It's that good! I say this because it helped me to understand some aspects that I did not "get" from the provided guide at a first reading.

It is interesting...quickly checking through the models, the only ones I could find which had x<>y shifted were the 17BII, 17BII+, 19BII, 28C/S (swap), 65 and 67. (For the 65/67, x<>Y and Roll down would be primary only if programs using the appropriate LBL had not been defined in program memory. Also, it is interesting that the 34C, 37E and 38E/C had x<>y primary, but roll down shifted. ...but of course, the purpose of articles like these are specifically for creating a dialog and I'm grateful that any sort of discussion might take place.

Heh. From your lips to HP's ears. Seriously, all of that material is in there. I have no idea how the quick start guide was written. The HP 10bII+ is a great little machine.
04-29-2011, 09:21 PM
Sure, right here:

Well, the quickstargt guide for the 10bII+ is essentially the "getting started" chapter from the original manual. A lot of the new things were put in there, but there wasn't enough space to cover it all. The QSG *is* enough for you to effectively use the machine however. Unlike the 30b QSG. :-) TW

Gene, how does a reference to HP's order page for a business calc answer a question about how to buy a third-party replacement processor for an HP-41? Am I missing something?
04-30-2011, 12:30 AM
doh. I mixed up the 10bII+ with the 41CL. No order page for the 41CL next set yet. Let Monte get the beta units out and in the hands of a group before he worries about taking orders for more.

Jake's new article has ancestors in 2008 as he mentioned in the last paragraph in HP Solve. Looking at them, you'll find tweaking is an hobby with a long tradition in this community, and also the wp34s has its parents and grandparents :-) Quote:I concur. OTOH only three scientific HPs needed one or both of these functions shifted. Jake listed them. Walter

Thanks for the info Gene.

Hi Jake, Thanks for the article! Actually of the three business calculators you mention (17BII, 17BII+ and 19BII) the X<>Y and RDN keys are printed as if they are shifted but they act as unshifted keys when in RPN mode. Marwan

Very good stuff.
05-01-2011, 05:31 PM
Concur, I prefer the swap and the roll down functions (and the STO function) all to be unshifted as well. The keyboard with three shifted functions (not counting the alpha characters) is a bit crazy. The key layout with the gold shift on top and blue shift on the bottom look the best IMO.
05-01-2011, 09:56 PM
Very good stuff indeed, thanks! I took the time to finally solve the cube resistor problem. I never did all the exercises in my textbooks (quite the contrary!). That one was in Resnick & Halliday's book, but I skipped in '82 :-)
05-01-2011, 10:34 PM
Nicely done. When I took first year college physics we called it "Halliday & Resnick", probably the 1st edition. (I must be pretty old because whatever edition it was the section on relativity was a supplement!) I need to dig it out and see if that resistor problem is in there.....
05-02-2011, 12:29 AM
I'll second that on STO! I guess the logic is that you use RCL more than STO so shift STO. However, I like the old Pioneer layout (and the 41 for that matter) with STO, RCL, X<>Y and RDN all unshifted.

Without nodal analysis, an overkill here, the trick would be redrawing the circuit connecting together the nodes clearly at the same potential, like 2 and 4, for instance. |
