Before the microcomputer most technologies were totally hackable and often buildable from scratch. Out of the things you had in the 60s, probably only TV could not be built in-house. Radios? Washing machines? Cars? All could be constructed by general population with various levels of effort. But what&#x27;s more important, all those things were user-servicable, user-modifiable and it was a popular hobby to tinker with stuff.
