They are remanufacturing this Classic 1977 Calculator


HP, finally recognizing the un-beatable layout
and fit & finish of various late 1970's calculators,
has finally agree'd to start a limited re-manufacturing
run of this 1977 model:

A representative from executive relations stated:

"HP built user-friendly calculators with
very powerful mathematics features in the late 1970s. But for remanufacture in 2003 with SAT scores and math aptitudes having declined significantly, we chose a calculator of the classic vintage but suitable for today's math aptitudes nationwide".

I remember that one. It never worked for me, though.

But since there's no way to key in numbers, I guess it didn't need an ENTER key either.

But semi-seriously now, suppose by some kind of magic, HP decided to remanufacture one of it's 1970's calculators. Which one should it be? No "updates" allowed to the machine's design.

(I'd vote for the 29C with the 25C as a second choice. Woodstock ergonimics just can't be beat!)

To me, it had the right mix of very useful features, and the keypad wasn't too cluttered or busy. The quartz timer was just the icing on the cake.

You said late 70s, I know. This one was introduced in the early-mid 70s, but was produced through 1977, which is late. So there. ;)



The HP 55 died prematurely.

If The Woz and company hadn't stuffed programmability into HP 25, the 55 would have lived longer. The original scope for the 25 didn't included programming. Don't get me wrong, I think The Woz did a great thing! :-)

BTW, the HP 41C *was* introduced in the late 70s, 1979 to be exact. That's my vote, the HP 41C. And _they_ might as well give it five times the memory of the 41C and call it the 41C5, but use the Roman numeral for 5, i.e., 41CV! ;-)

The Woz? Are we talking about the same person here? "The Woz" is what Apple Computer personnel (and Macintosh fans) call Steve Wozniak, the co-founder of Apple Computer (along with Steve Jobs).

If you're talking about the same person, how did Wozniak end up having decision powers over Hewlett-Packard calculators? As far as I know, there has never been any link between Apple and HP, except as far as HP's printers is concerned.



Woz worked for HP for a while during the mid 70's before leaving to work full-time for Apple. IIRC, he sold his HP 45 (and Steve Jobs sold his VW Bus) to raise the initial capital to begin producing the Apple I.

Steve Jobs worked for Atari for a while prior to starting Apple, and he and Woz (probably more the latter) designed the original "Break Out" arcade game.



One learns something new every day!

Thanks for the information. It's pretty interesting. Perhaps I shouldn't have been so amazed at the news, considering that both Apple and HP are in the same geographical area and both make electronic products.




For some additional insight into Woz's sideline "activities" while working for HP, you may want to read this HP Memories article by Andrew Burg.


I apologize for not checking the Forum for a while.

Yes, both HP Advanced Products Division (APD) and Apple were in Cupertino, California (USA). I think I heard about The Woz and the HP 25 from Paul Ceruzzi. Paul works at the Smithsonian Institution.



imho: 70's 80's or 90's - it's all the same. the 41 is one of the three or four finest implements ever designed by the eye and hand of man. for one example; there were a few calculators which like the 41 were powerful and reliable enough to be used for air and sea navigation. one was even a ti. the list of calculators trusted to fly spacecraft gets real short. and if you don't like something about the 41 then stroke the user key and change it.

i just got one with a standard applications book and i'm in love. guess it shows.


Well, in addition to the 6-button special that is
in fact being remanufactured,

my vote is that they should re-manufacture the HP-34C.
The HP-34C is on-par with something Biblical, like, handed down thru the clouds to Moses.

MEANWHILE, about that re-manufacture, as a topic,
they do re-manufacture gadgets from time-to-time,
but the remanufactured version is often strikingly
inferior to the original. So, what if its not the same ?


I bought one of those "Mattel Football" games that
has been remanufactured. Despite obviously higher
complexity, they changed the display all around,
maintaining outward appearances but different by design.

The original used real LED's, dirt-cheap little
segments to represent the game.

The new one (presumably since there aren't any more LED's)
is actually based upon an LCD. There are continuously
illuminated "backlighting" red LED's. The LCD ports
thru an obviously tiny fraction of that energy, by
letting a bit of light thru where the LED's were supposed
to be.

For all that stinkin' foolin' around, they could've just
remanufactured the genuine item. BUT NOOOO they had to
build it with an LCD, because presumably they could just download the computer file to "NIPPON CUSTOM LCD FACTORY" by using the internet, and be real lazy, and not figure out how to actually build anything.

So, it really doesn't act quite the same. And on my unit,
if you rub your finger over the plastic, it will temporarily
"erase" the whole display due to static charge having
an overwhelming effect on the LCD.

For these reasons, if you want one of those 6-button
Mattel Classic Calculators, you'd be well-advised to go
seek an original. Mr. Grubby Enron MoneyBux can't even
replicate his own recipe for success in this and many other situations.


And speaking of 41C and space, Since I am working with NASA currently part time, I had this web page marked, can't recall if Dave has a link to it or not.


Why do you think they stopped making them? Cost!

Successive models came out because they could be made cheaper.
