Self Inflicted CARNAGE! ZX Spectrum Repair

Special thanks to PCBWay for sponsoring this video. https://www.pcbway.com/ Today I tackle a dead ZX Spectrum from a huge box of retro repairs.

Patrons get ad-free early access to videos, behind-the-scenes updates, and entry to a super secret Discord channel — plus my sincere gratitude, which is worth roughly what you'd expect. ▸ Patreon: https://www.patreon.com/c/morefunmakingit ───────────────────────────── I also have another channel called More Fun Making It, where I build things from scratch instead of trying to coax life back into them.
