+55 photosCould not fixSharp — X68000
A proper exercise in stubbornness on this Sharp X68000. Two rounds of repair, a full recap, FDD surgery (one of the floppy drives had clear signs of a blown capacitor with charring on the PCB), a new oscillator, and still no picture. The X68000 remains on the 'future date' pile.

Absolute labour of love on this Sega Wondermega HWM-5010 from Japan: corrosion, missing components, broken traces and a RAM package with broken legs. The Mega Drive side eventually came back to life; the Mega-CD side continues to freeze on the BIOS animation, defying everything thrown at it.

Proper saga on this Sharp X68000 Pro II. Magic smoke from a reversed capacitor, an accidental probe short, and enough replaced components to fill a parts drawer before a single faulty transistor finally gave the game away. Got it booting and running R-Type, which was a hard-earned win. Video output later stopped working, so the story isn't entirely over.

Three 9-inch Sony PVM-9040s that arrived from Japan with customs drama. Monitors were fine inside, bar a known colour issue fixed by replacing the trim pots (which fixes the black-and-white-only fault). Full restoration across all three followed.

This Nintendo Super Famicom (SHVC-001) would not power on due to a failed D1 diode. Tracing and replacing it, plus a recap, had the console booting again.
