Dave Poo 2 | Installing C64 RF Modulator Replacement on a PAL Longboard @DavePoo2 | Uploaded April 2021 | Updated October 2024, 1 hour ago.
I've built a C64 RF modulator replacement and i'm installing it an Breadbin C64 longboard. There were a few problems after installation with the ground on the modulator, which might be specific to PAL longboards that are using this modulator replacement.
