ABSTRACT
At that time our department wanted to buy a desktop calculator, about the size of an old-style typewriter, for £1,200. A lecturer in the Engineering department advised us to wait. He showed me the first hand-held calculator I had ever seen, a small half brick, purchased in America for a mere £400 and it had four memories. Four memories – wow! Today’s equivalent would probably come free with a packet of crisps and weigh an ounce.
