Collector's Pack

As many of our visitors are calculator collectors, we have decided to make their hobby easier, by joining all HP calculators in four groups:

 

 

We are adding all calculators in each group and reducing their price by 20%. In that way, we increase the size of the sale, and you get a significant discount. In the case of the first of them, the financial pack, you save 97,86 €! (apart from lower shipping costs)

The financial pack is composed of:

HP10bII+

HP12c

HP12c Platinum

HP12c Anniversary

HP20b

HP30b

HP17bII

In later days we will complete the offer with the other bundles. I hope you like it!

New flashing service

Today I have received a USB to com adaptor. Since most of our computers are laptops and quite new, we did not have serial adapters. I have then proceeded to update a 12c+ with the latest available software. In this particular case, it did not increase speed (it was already 150 times faster, so I am not deceived), but it corrected a number of issues compared with the original firmware.

We have decided to offer firmware flashing as a service for our purchases of a calculator. It will have a 10 € charge. The rules:

  • Calculators elegible for firmware flashing are HP10bII+, HP20b, HP30b, HP12c (ARM version)
  • The customer supplies the firmware through email.
  • The calculator to be flashed will be a new, out-of-the-box (or plastic package!). The serial number and proof of purchase bits of the packaging will be included in the shipping to the customer. (It is the customer decision to register the calculator in HP's website). Sorry, we will not flash calculators not brand new!

One of the most exciting projects is the repurposing of the hp20b and hp30b financial calculators with ultra-slick scientific firmware. The project is called wp34s and is run by Marcus von Cube, Walter Bonin and Paul Dale (in no specific order!).

You can find it on http://wp34s.sourceforge.net/

There have been a number of releases (build number was 800 at the time of writing), and you can check whether you like the software by running the included .exe file and testing the features. The .exe file has the advantage of having the right labels on the keys!

I have not yet tested the flasher cable and software on a HP30b but I plan to do it shortly. I will then report on the results!
