HP's New '70s-Style Retro Calculator

HP Celebrates 35th Anniversary of Landmark Calculator

Most of our readers are probably too young to remember the slide rule. An archaic device for doing arithmetic that was the standard before the arrival of high powered and practical pocket calculators. HP is continuing its year long celebration of its 35th anniversary by honoring the device that almost single-handedly killed the slide rule -- The HP 35.

To mark the 35th anniversary of this engineers' favorite, HP has released the HP 35s, a powerful programmable pocket calculator (oh alliteration) in a design reminiscent of the original HP 35.

The new calc has much more memory, more functions and sadly ditches the original single line LED display for a two line LCD with adjustable contrast. The HP 35s is also only $60, compared with the $395 the original HP 35 fetched.

WOW !!
I had them all. First the 35, then the 45, then the 65, then a 41, followed by the C and V versions. Best one of the whole bunch was the 41 CX with the card reader strip, and the printer jack.
I still have that 41 but sadly it quit working several years ago, and I could never find anyone, including HP, who would, or could, service it.
Does anyone out there know who could get my old 41 working??? Maybe, with newly spiked interest in the (new) 35, HP will come to their senses, now that Carly is mercifully gone, and re-instate a service to do so.
Any ideas??

John T: Hi John! I love the 41 series, they're wonderful machines! Your CX is probably quite serviceable. The most common problem is cracked posts that prevent the internal pressure pads from making proper contact for conductivity.

There's a fellow named Randy Sloyer who fixes HPs, and has a very good reputation. Check out his website at http://www.fixthatcalc.com/ . He has quite a backlog because he's very popular, but I've heard nothing but good things.

Good luck!

I remember the Texas Instruments TR-10 getting me off the C and D scales of the slide rule in 1971. I had to charge it regularly..it didn't take batteries. It looked similar to the HP-35, but simpler...
