The Ultimate Version of the Worst 1980’s Micro?

A huge thank you to the sponsor of this video https://www.pcbway.com

Building MY Ultimate 1981 Home Computer – The ZX81+38 This isn’t a repair or a restoration—this is a full custom build of what I consider the ultimate ZX81. Starting with a ZX81+38 PCB designed by Mahjong, and packing modern components, a custom 3D-printed case, a mechanical keyboard, and a healthy dose of retro bling, I’m building the machine I wish I’d had back in 1981. Along the way, I’ll talk about the history of the ZX81, my own childhood experiences with it, and what makes this build so special. From hand-placing components to solving composite video output quirks, and from mechanical key switches to custom keycaps, this is the full journey from bare PCB to fully working, souped-up Sinclair classic. Whether you had a ZX81 of your own, or just enjoy watching someone pour far too much love into a tiny 8-bit machine with 1K of RAM, I hope you enjoy the ride.
