Something even more fundamentally desirable than over-marketed computing equipment, we suspect - a technicolour wantonness that should be de rigueur in the world's louchest nightclubs next summer.

That was impossible: the amount of computing equipment required simply would not have fitted in the vehicle and would have had to be hauled round on a trailer.

Battery rooms are found in telecommunication central offices, and to provide standby power to computing equipment in datacenters.

The availability of smaller, more powerful and less expensive computing equipment made electronic data processing within the reach of small business and the home user.
