A Dreamcast VMU from a real barn find, covered in animal muck. I strip, sanitise and polish it, fix the loose buzzer wire and see if it still works.
A leaky Amiga A501 half meg expansion caught in time: battery removed, alkaline leak neutralised with vinegar, and a test with early 90s cover disk demos.
The parts have arrived for the smashed Mega CD. I recap both boards, fit a save battery and a new pico fuse, repair a broken track and live test it.
A rusty, dented Mega CD 1 arrives in a bag with its battery torn off and every SMD capacitor leaking. I strip it down and work out what it needs.
A full PS4 DualShock 4 teardown: replacing worn thumbstick grips, changing the battery, cleaning the buttons and refitting the fiddly triggers.
