🛠 Check out PCBWay at https://pcbway.com for all your PCB needs! 🛠 The sinclair ZX81 from 1981 is an iconic retro computer in the history of home computing. The follow up to the ZX80 Sir Clive Sinclair consolidated many chips into a ULA to further cost reduce the computer and help get it into our homes from under £50. A truly low cost computer. Today we take a look at one, repair it and try it out to see how it holds up today. 🏆 Support RMC Time is the most valuable thing we have.
