Sinclair ZX81 Spruce Up (Composite, 16K, Keyboard & More!)

Thanks to PCBWay for sponsoring this video! Check out their KiCad Open Source Design Contest! https://www.pcbway.com/activity/kicad... In this video I finally get a chance to play around with the ZX81 I picked up back in September 2023 at VCFMidwest. In my younger days I may have chuckled at this thing but as I've gotten older I understand and appreciate the role this little computer had in computing history. I think for many folks this was their first computing experience just as mine was with a hand me down VIC-20. I didn't even know if this thing worked when I bought it. Watch and see how things go!
