More about the book

The ZX81, launched in 1981 by Sir Clive Sinclair, revolutionized home computing with its low-cost design aimed at the general public. Selling over 1.5 million units, it also inspired numerous unauthorized clones, particularly in Eastern Bloc countries. Consumers had the option to buy the machine pre-assembled or as a kit, promoting a DIY culture that encouraged hands-on learning. Enthusiasts explored its capabilities, sharing programs saved on audio cassettes, making it a pivotal tool in the early computing landscape.
