This is a scratchpad for some ideas I've had involving how to route audio and video from a CX-55 VCS Adapter in a 5200 with a UAV installed.
First order of business: recap the current CX-55 and replace the voltage regulator. The video looks awful. The video looks awful when viewed via the 5200, which has a snow issue over RF that is likely in the modulator. If the modulator's in need of work to improve the 5200's video, then the same will apply to the CX-55's video.
Next: build a circuit to power it and pull both audio and composite video directly from its edge connector. Need perfboard, a barrel jack (power), small toggle switch (power), and RCA A/V jacks. Cartridge port connector and A/V cable are already on hand. Everything is THT at 2.54mm. Current-limiting resistor / filter cap / both may be needed.
CX-55 cartridge connector pins:
24 Composite Out
25 GND
26 +5VDC
30 Audio Out
Alternative ground pins: 12, 13, 14, 23
Unregulated DC on pin 11
Pins 11 & 28 not connected (possible chroma / luma outputs?)
Determine if audio / video levels are suitable for use without further amplification.
