Calculator blog

The early orders for the HP15c Collector's Edition have all been shipped. From now on, it is business as usual - normal ordrs coming in and out.

705 orders have been fulfilled for a total of 937 calculators. Several people decided to take 2 or more calculators, profiteering from the discount for more than 5 and more than 10 units built into the price structure.

And in many cases the customers have already received them. We did not use the postal system, just courier companies, with typical delivery lapses of 2-3 days within Europe. 

The HP15c first batch of units entered the Moravia warehouse on July 19 - here is how they look! We will ship them to our customers as soon as they reach us!!

Forgot to mention that this week the units left the Philippines and are on their way to Moravia in Czech republic. From there, immediately to us and then to you!!!

Also, answering a question to one of our videos in youtube: the firmware date is 2023-01-05

I receive many questions about the leather case for the HP15c CE calculator. 

The first thing to answer is that there you will have the standard case in all cases: choosing the leather case will get you the standard case that is in the box + a leather case.

The second thing is taking a look at the pictures of both:

...And here is how they look!

(Please also see the HP12c running HP16c firmware !!! )

We have received several questions about the Overlay option in the HP15CE - so many that we have changed the name to "Cover". 

It is an HP16c overlay to be put on top of the keyboard. It allows the machine to behave as an HP16c if you have the means to transfer there the firmware of an HP16c. It is possible on the newest versions of the HP15c or the HP12c too (NOT Platinum). More details to come in following weeks!

There will be another option for HP15c cover too.

This HP16c overlay version has a little blurred yellow print - the jet seems to be too far from the surface. We'll receive it in a few days to try it mechanically - how it works. It can be used in any new Voyager calculator with the suitable firmware (HP12c -attention, NOT Platinum-, or HP15c CE)

Here is another picture fo the tests we are doing with overlays. difficult to get the process to get the colors right! Also the blue labels are still not well centered - next tests tomorrow! At least the keyboard works well and adheres well too: you need to shake hard the calculator to get it out. It will work well on that count!

We are in the final stages of preparing a cover for HP16c. The software will have to work on other "new" Voyager calculators. We have suitable firmware to do it. We are testing it, but I do not think we can run a fully-fledged testing process for it. We will have to work with it as is.

This is a printing sample of what we want to achieve:

It does not fall from the calculator, and can help you use your voyager calculator as a HP16c - the long-gone computer scientist calculator.

Will it work with the new HP15c Collector's Edition? If we can make it work with the latest HP12c, of course it can!

I cannot help but buy calculators that I like. The other day I spotted a 1987 HP12c calculator in quite good shape. It was still working, but the battery low indicator was blinking all the time. The way the calculator looked, it had not been used too often - so the batteries may have even been original! These calculators' batteries really lasted forever. Also the clicking of the buttons is like the original - clear clicking, but softer keys than the ones of the new HP12c.

But the nice thing of this calculator is that it came with the best leather case.

This time in Burgundy - I had it in the past in brown color, but never in Burgundy!

I still don't know if I'll put it up for sale, or with/without the case, or with my own leather case.
