This will get a much longer writeup but I've been fixing up a broken PXL-2000 that records video to cassette tape. RF output didn't work so I performed a composite video mod. Then the lens assembly was wonky so I modified that. Soon I'll add some RCA connectors and clean heads.
@Famicoman Understood, similarily I used to be in a Gameboy Camera Funtography group a decade ago. I remember seeing a website dedicated to the PXL over 25 years ago (and probably long gone), am sort of impressed there is still an active userbase.
