But didn't you hear about the classic problem with the trig functions on Casio FX-850P Personal Computer ...LOL

I never had a Casio SF-7500 but I did have a Casio FX-850P Personal Computer. In fact I still have it some 25 years on and it still works.

Its an amazing device I used for storing names and phone numbers but best of all it came with the Basic language and 10 slots to store programs.

It got most of it's use during the construction of Sizewell B Nuclear Power station in Suffolk England, where I used its trig functions to calculate where I had installed stress measuring instrumentation within the cylindrical wall and dome of the reactor building. A surveyor would give me some measurements from known datum points and from that I could calculate the instruments radius, bearing and height within the building. Oh the memories of crawling around in steel work and concrete.

If it weren't for my smart phone, I would still be carrying this thing around. I don't think I will ever through it away even if it stops working.

Lost data

 If so, are you aware of any techniques the designers used to compress the data and take maximum advantage of the limited resources?

Not only am I unaware, I can remember two instances where similar devices broke and the data was irretrievably lost because they couldn't be linked to other devices.

Compaq iPaq

In the meantime, did you ever own one of these devices (or something similar)?

When my brother passed in 2003, I inherited his Compaq iPaq (similar to this, although I don't think it was colour). I did try to get myself computer calendar literate, but there are two problems. Firstly I hate having something hitched onto my belt or in any of my pockets. Secondly it seemed to need charging every day or two, so I would have to develop some kind of discipline. It never took, nor has anything else. Despite the calendar on Outlook, a mobile phone (dumb, but still with a calendar/ appointment function), an iPad and a Microsoft Surface I still write everything down in a paper day-timer. Notwithstanding my work in this industry, apparently this dog can't change its spots.

I don't know why it is that these old digital machines seem so cool -- even though they have so little capability as compared to modern devices.

Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
