Please take a look to the Blue-white HP 50g
It sure doesn't look engineer-like but school-like; but then, most of my customers for this product are in college!
There have been discussions as well about label contrast and readability - despite its looks, methinks this one scores high. Take a look at this close up. Sorry for not taking it out of the sle...

The new HP10bII+ has arrived!
A complete review will appear in a future blog instalment - I am too excited to wait for that and will just give you my first impressions.
While I love RPN machines, I have to accept that this one clicks more than some buttons in my heart. Three pictures will suffice to see what I mean:
Look at all buttons fill...
A trace mode "accountant type" for the HP 50g
Publicado el por JGD
If you have an HP 50g and you want to print something, your best way to printing is the HP 82240B. The distance betwen printer and calculator must be very small (around 1 inch), and the list of printing commands is not too big, in particular if you want to print accounting calculations like you would do in the 17bII.
I am sorry to come back to finance-rel...
A comparison between HP 17bII, HP 17bII+ gold and HP 17bII+ silver
Publicado el por JGD
I wanted to check how the new designs fare when compared with the old Pioneer series. Here you have my impressions:
Key feel:
The original HP 17bII wins, hands down. Second, and not too far from it, the HP 17bII+ silver. The slanted keys of the latter are more comfortable to put the finger on, but the rounded keys of the original ...
Just received my first 30b - first impressions
Publicado el por JGD
Today I opened the box of the 30b and had my first stint with it. I will do a formal review in some time from now, but cannot avoid making some comments on the fly.
To give a reference, I think that the best financial calculator is the HP17bII - from the viewpoint of having all of them. I think also that the latest HP17bII+ is the best of all, followed by ...
The HP85 and my 7 year old

This last Saturday my 7 year old asked me about the green suitcase in the mountains cabin. "What's this, Dad?
"A portable computer, Guillermo"
"That big? Can I see it?"
"Yes you can"
Convert HP15c in a financial calculator - in addition to be one of the best scientific there were!
Publicado el por JGD
Let's start a short project.
As engineer, I tend naturally to scientific calculators, but in the daily life we need to get into business more often than not.
You need to discuss the profitability of investments, their net present value, and several value of time issues. That is, IRR, NPV, TVM. While it would be good to have flows as long as you need, in my company all projects are calculated over 10 years - except acquisitions, and these are not ...
New products coming
Publicado el por JGD
Our contacts in HP have informed us about several new products in the pipeline. There are ultra-new things and some less new (to say the least) in the works. Estimated time of arrival on European shelves is July - maybe announcement will come sooner.
One of the calculator projects will likely sell in the millions (not hundreds of thousands - millions!) but the other will be a limited run of 10000 units - and that's all.
HP revamped their calculator strategy several y...
New HP50g vs Classic 15c
Publicado el por JGD
I see the old HP15c derided by current users by comparing it with HP 50g. They laugh at the specs, the screen size, the programming model, etc. They wonder how mint units can get over 300 € on ebay and other sites.
I have both. In my common work, I use the HP 50g. I can see everything that I have done - sometimes I need to clear to unclutter the stack. However, it is clear...
My HP calculator history (I)

At the same time, I had access to a HP85 computer. Now I see it called a "calculator", but at that time it was considered ...
