Casio PB-110 I came across this on Sunday whilst at mum and dad's. I bought this when I was about 13/14. It allowed you to do some nifty little things - you could code in basic on it for starters. Now hands up who knew of my geek credentials? This 'Data Bank' is retro geek chic and no mistake. PS. If any japanese collector wants to pay top dollar for this... get in touch by clicking here.
