C64-RF-Modulator with S-Video Mod
This is a project of a modulator replacement based on an analog c0pperdragon module. It was adjusted in size to the Commodore C64C motherboard and extended with S-Video and Strereo Audio outputs.
Changelog:
1.2
- internal audio route to left and/or right channel
- ferrite beads to suppresses high-frequency electronic noise
- silkscreen layer with descriptions of all outputs and elements
- 3D models for a nice rendering
- project cleaned up and migrated to KiCad 6.0
- interactive BOM
1.1
- prototype fixes
1.0
- PCB size adjusted to C64C motherboards (ASSY No.250469)
- S-Video connector added (mini-DIN 4)
- added standard stereo audio mini-jack 3.5mm output
Bill of materials:
Final revision:
- all jumpers removed: audio output from an external source (e.g. MixSID)
- all jumpers on: mono signal from the motherboard connected to the left and right channels
Prototype images:
The board connected to SixtyClone. Image from S-Video output:
The board can be soldered with pins to the motherboard. Then the S-Video and Audio outputs will be at the level of the corresponding openings in the housing.
