The popular quiz in which mummy, daddy and the little ones take on an opposing family in a test of general knowledge is now available in a version for the Vic 20.

One team uses the space bar as a buzzer, while the other uses the function keys. It's almost the real thing as the teams crowd round, fingers hovering over the buzzers, to strike first. All that's missing really is the genial, but sometimes sharp, chairmanship of Robert Robinson.

The program loads in two parts; the first cassette holds the operating system and the second contains the actual questions.

Once loaded however, the program is straightforward. Questions are offered first to one side and then, if they are unable to answer, to the other.

There is a good variety of questions on the program including general knowledge, spot the music and IQ test-style puzzles. For instance, who wrote the opera Death in Venice? At what temperature are Fahrenheit and Centigrade the same?

So the questions are neither ridiculously easy nor outrageously difficult. The computer's limited range of responses, though, can become very annoying. Sometimes it patronises you if you get a correct answer: 'That's just the answer I'm looking for.' Get it wrong and it sympathises: 'I'm afraid not.' Pretty soon you feel like punching the smug creep in the VDU.

But the main drawback to this program is that it contains only 120 questions - hardly enough to make it one you will want to return to.
