Sinclair ZX80 and ZX81: The cheap Sinclair home computers

In this video, I take a deep dive into the legendary Sinclair ZX80 and its successor, the famous ZX81. We'll look at the unique hardware design, its internal PCB, and how Sir Clive Sinclair managed to bring computing into the home at an affordable price point. From the membrane keyboard to the primitive but iconic hardware engineering, we explore why this machine is such a vital piece of computing history.
