MEGABUCK'S AND MEGABYTES

            Computer software has made Joyce and Larry L. and their family rich enough to build their dream house - an enormous computer-controlled mansion complete with swimming pool, baseball pitch, miniature estate cars for racing round the grounds, and tennis court, in a leafy Dallas suburb.
             There are so many rooms in the house itself that to send messages to family members they need intercoms, absolutely essential in a house where it could take half an hour to find somebody.
             It is morning in the kitchen. Sitting in line at the huge breakfast bar in order of age from two to eleven are their seven children. The daily printout from the master computer in the attic with its five gigabytes of memory has already told them what the day holds for them by producing a list of activities for each member of the family. The computer has also recorded the outside temperature, the air pressure, the wind direction and speed. Inside the house it controls the lights, the room temperatures, each child's computer , the back-up generator, the tv sets and the massive security system which protects the property. .
             In addition to the main computer, each child has his or her own computer station, complete with laser printer, just like Larry's.
             It takes an army of helpers, dozens of machines and clockwork precision to make it all work. But then precision is something the family knows all about, for this is a house that computers have designed. Larry is the founder of a company which has built up its business providing computer software for small firms. Larry talks as he takes us on a four-hour tour of the mansion.
             "I've always been fascinated by computers. In fact, i was brought up with them- worked with them since the age of fourteen! I've been lucky, though, because I've always had good people to work for me. But I think my real strength is that I've done every single job in the company myself, so I know just what's involved in each one.
