Raspberry Pi.

V and I went to a computer show in Wakefield today, the first we've been to for several years.

I bought my first ever computer in 1979 in the days when you had to build them yourself. I did manage to get mine ready built, an Acorn Atom with 8Kbs of Ram and the same sized Rom. Input/output was via a cassette recorder.

Acorn went on to produce the BBC computers which were very advanced at the time. Then came the Archimedes series and finally the RiscPCs. Acorn left the computer scene then, leaving the machines with another company and the operating system known as Risc OS with a different company. They changed their name to Element 14 and went into the set top box market. Acorn's main legacy is the ARM chip which has continued to evolve, now under different ownership, and is present in more devices than the average man in the street would ever imagine.

Risc OS continues to flourish and is presently undergoing something of a revival since the appearance of the Raspberry Pi in 2012, partly developed by Element 14.

The picture is of a Raspberry Pi, a 'credit card sized' computer. Its size can by gauged by examining the HDMI lead sticking out of the bottom of the device, the USB stick on the right hand side and the SD card on the left hand side.

Needless to say I bought one.
