It should not be too surprising when you consider the magnitude of the TI-30 and TI-80 series marketing collateral. Having supplied algebra and mathematics textbooks to almost every public school and many colleges in the country, textbooks that just happen to include keystroke-guided how-tos, it is no mystery that TI is inclined to continue with the form-factor and user interface. Because of the successful effort embedding their product into the curricula, TI calculators are now the defacto standard for what-to-buy lists in most school districts. Hats off to the TI guys that thought of this; our "educators" bought it hook, line and sinker.

P.S. Its more than 2 decades -- TI-30s were available in the late 70's.

I bought one of the first HP-55 programmable calculators in, I think it was, 1975. I had to send it in once under warranty, to replace the super-cheap power switch, which was a slider making contact directly on copper traces on the circuit board! But, otherwise, it was a great calculator: Over 3 hours between recharges of the NiCd battery, and it combined a programmable calculator and counter/timer.. After I upgraded to an HP-67 (same stupid power switch!), I soldered an electrolytic capacitor into the battery compartment, and I still use it that way, with power adapter plugged into a wall socket. But, I don't calculate any more with the HP-55: I've had it continuously turned on, with the counter running for over 30 years now, as a way to detect whether there has been a power failure while I was away at work. If the count has stopped, or the display is garbled, I know my AC line has gone down! They don't make them that way, any more.

Are you sure? I purchased an LED based TI calculator in the mid 80's. Very expensive and ate the battery. When were LCDs in common use?

I got Casio FX-81 as a gift in year 1981. I am using the same calculator for almost 30 years. Also, I changesd the orignal Casio battery only around six months back! What a wonderful engineered product.

I bought a SEIKO automatic wrist watch in Chicago in 1979. Till date this watch is working perfectly and needed no maintenance except may be some cleaning and greasing by my local watch repairer. About ten years back, when there was too m uch of a craze for digital watches I bought one digital watch and kept my Seiko in a drawer. That digital watch lasted for only about three years and I switched back to my old Seiko which started functioning at the flick of my wrist. My hat off to Seiko for such as masterpiece of engineering which has lasted almost my active life-time. All these mechanical watches are in fashion again. They have lasted the test of TIME!

How do you define "high-tech"? Not only have carbon-zinc dry cells had little exterior changes, but the internal workings have also been virtually unchanged for roughly 100 years. I suppose they're no longer considered "high tech" but that also points to the relative transitory nature of that term. No doubt many would no longer consider the Walkman high-tech, though it was 30 years ago.

What about all of those LED alarm clocks? I noticed that a new one was constructed with modules strikingly similar to my old one from the 1970s - right down to the PMOS LSI chip!

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
