 In the 1980, many computers were not put in living rooms, but (childrens') bedrooms, attics, basements or even workshops to control wood- or metal-working hardware. Those places tended to be prone to much dust, and the computer was only on for a few hours a day. Consumer products quite often were prone to mechanical jams due to dust, so especially in professional workshops, covers were regularly used. Industry DP was often so prohibitively expensive that home computers - quite often the C64, but the CPC offered a Z80 and CP/M as a boon - popped up in the most curious places (eg. a C64 was used to control the water supply of a German commune in the mid-80s).

+Dust Covers are especially molded plastic or wrapper covers to protect the CPC from dust when switched off.

 Today, Dust Covers are more or less unknown. But, they have left some scars: Many people still feel irrationally guilty when exposing computer hardware to dust. The dust cover phenomenon (eighties) can be compared with the hype for equally useless ''mouse pads'' (nineties), ''protective foils'' for LCD screens (first decade of 21st century), and ''sliced bread'' (thirties).

 There are no known laws against producing, distributing, or even using dust covers. However, users are likely to lose their precious warranty if a computer catches fire because of covering its ventilation holes after forgetting to switch off the power-supply. Fortunately, the dust cover users never realized that dilemma, otherwise they'd have probably died from a heart-attack when trying to find a solultion to the question: Risk the warranty, or risk the dust?
