Oric Repair: The "Impossible" RAM Failure

About this video

Why would an Oric Atmos show an "impossible" RAM failure? Noel's Retro Lab expects a fairly routine repair and ends up hunting for where the fault really lies.

Good to know: Board level fault finding. Soldering brings burns and fumes, and old solder contains lead.

Why watch it

Tests kept pointing one way while the maker's instinct pointed another, so this is about doubting a test result, not about swapping one chip.
