I AM SO SMART, I AM SO SMART [92]

I expect my phone to access the internet, read PDF documents, show me a map of the local area, and count how many steps I walk, but I have no need to use it as a compass, calculator or spirit level, even though I could. In fact, I take some pleasure in having a small pocket calculator in my bag – I can only ask one job of it, but it does that job perfectly. Likewise, I write my articles using a word processor, not a computer.

The AlphaSmart Neo word processor was made from 2004 to 2013, the latest in a line of machines begun in 1993, from a company set up by two former Apple Computer employees. AlphaSmart’s intention was to create an affordable device for learning in classrooms, as multiple processors could be connected for tasks and lessons – the final processor in the line, the Neo 2, could also run class quizzes. However, its main function is as a digital typewriter, small and light enough to carry anywhere, but with a full-sized keyboard, for the simple entry of text onto a LCD screen, automatically saved to be uploaded via USB cable to your main computer later. With no wi-fi, cloud computing or internet to worry about, three AA batteries will last for up to SEVEN HUNDRED HOURS of continuous typing.

I bought my AlphaSmart Neo for £20 on eBay four months ago, and I am still using the original batteries. It is ready to type within three seconds of turning it on, more immediate for entering an idle thought than finding a pen and paper - because I only use the word processing program, the machine will always boot into a cursor flashing ready, provided you remember which of the eight available files you selected last time. Total memory is only 512K, or 0.0005Gb, but that is enough for two hundred A4 pages. You can change the size of the text on screen, but you cannot make it bold, italic or underlined, as you do that when you upload your work later. I can simply connect a USB cable to my main computer, open a word processing program, press “Send,” and my text flies onto the screen, like it is being typed especially quickly – watching the screen fill up with your first draft is very satisfying.

The decline of the AlphaSmart corresponded with the rise of far more flexible tablet computers, and the general reduction in the cost of computing. I have a Bluetooth computer for my iPad, and have written articles on it before, but I personally find it far too easy to flick between apps to find information from a website, only to return to my word processing app after an hour or so has passed. To have a machine that requires you to concentrate, and to keep typing until the job is done, is useful enough, but it requires the maker to forego building a device that can anticipate and accommodate possible future uses. If you don’t need that, it doesn’t matter.

I think there could still be a market for the AlphaSmart, at least in the way I use mine. A recent Kickstarter project was the Hemingwrite, later renamed the Freewrite, essentially a typewriter with an aluminium body, e-ink display, rechargeable battery, wi-fi cloud support and a carry handle, but costing around £400 – the “set your writing free” philosophy of its manufacturer, Astrohaus, is pitched more towards creative writing than to work. What would I do? Take a one-chip microcontroller device, like a Raspberry Pi, load a simple word processor program to it, attach an e-ink or LCD screen, add a keyboard, battery and USB port, put it all into a box the size of a small book, and sell it for about £60. I nearly made one myself, until I found that AlphaSmart made the perfect device years ago.

ONE SHAFT OF LIGHT THAT SHOWS THE WAY [86]

Last weekend, I took delivery of a piece of my childhood: an Acorn BBC Micro computer. For an entire generation of British schoolchildren, the BBC Micro, introduced in 1981 as part of a Government-backed computer literacy campaign, cemented Acorn as a British technology success story for nearly twenty years, culminating in the creation of the ARM chip, now found in billions of devices.

Why did I buy a second-hand one on eBay, described as being “in working condition, needs a clean”? Apart from having already bought another BBC Micro eight years ago, sadly no longer working, I wanted to make some music with it – the four-channel Texas Instruments sound chip installed in it is also found in other 8-bit machines, but also many Sega arcade machines, the Master System and the Mega Drive / Genesis. In addition, BBC BASIC, created by Acorn engineer Sophie Wilson, is still the most versatile version of BASIC, with easy SOUND and ENVELOPE commands to build sounds – Commodore 64 owners, in comparison, are left to POKE their sound chips until they made a noise.

In a time when we expect our mobile phones, let alone our computers, to be capable of more than everything, the BBC Micro, and other 8-bit computers like the Sinclair ZX Spectrum, the Apple II, and the Amstrad CPC464, all appear to be as capable as the micro-controller chips you might find in your alarm clock or hi-fi system. That is sort of correct: Acorn’s first computer, the System I, looked like a calculator, was programmed directly to the processor using hexadecimal machine code, and was developed from a cow feeding system.

Modern micro-controller systems, like the open-source Arduino or the Raspberry Pi, take computing back to the same nuts-and-bolts principle of writing your own programs, and building your own devices. Using the BBC Micro at school was Eben Upton’s inspiration for creating the Raspberry Pi, and eventually led the BBC to produce the Micro:Bit micro-controller board, returning to a computer literacy program when programming skills are needed more than ever. The Arduino system was easy enough for me, an enthusiastic bystander when it comes to computing, to consider building a type of electronic typewriter, where you could enter text without the distraction of the internet, and upload it to your computer later -  however, the Alphasmart series of keyboards already did this, so I have since bought one of them.

Likewise, the BBC Micro has been used as widely as the on-screen ident generator for Children’s BBC, the steering controller for a radio telescope at the Jodrell Bank observatory, and as a music sequencer on the Queen song “A Kind of Magic.” My older non-working Micro could also save programs to SD card, through the successful fusion of old technology with the new.

What did I make of my “new” BBC Micro? Erm… It turns out there is a known issue where the capacitors in the internal power supply will eventually fail, because thirty seconds after turning on the thirty-plus year-old machine, the sound of firecrackers, made without any programming from me, was followed by quite a bit of smoke. It would have been nice to make retro computer music using period equipment, instead of resorting to attaching a music keyboard to my iPad, but soldering capacitors is more than a bit beyond my capabilities – at least, I did get my money back.
