Repairing a motherboard with a subtle intermittent fault

Adrian's Digital Basement ][ 2h 55m Published Jan 2025

About this video

An intermittent fault on a CompuAdd SCAT386SX motherboard takes a long diagnosis, one of the hardest the maker has dealt with. The C&T chipset datasheet is linked.

Good to know: Board level fault finding with test gear; soldering brings burns and fumes. Jumper and switch notes were saved to The Retro Web.

Why watch it

Persistence is the theme, since the maker wanted to give up on this board but kept at it, and the video is billed as a true long form diagnosis.
