The RGB4ALL is a universal video converter based on AD724 chip. It takes RGB signal on an input, encodes and outputs it to more convenient Composite video or S-Video sockets which are more often seen in modern TVs.
It was tested with Amiga 500/600/1200, Amstrad 464/6128,Neo Geo MVS and other hardware that outputs RGB signal.
Some people succesfully implemented it in Atari ST series and in other hardware such as car screens.
Installing it in a machine with an NTSC circuitry is possible but requires re-soldering quartz oscillator.
Please remember to change SJ1 solder blob to proper position if using NTSC mode.
There is PAL quartz oscillator soldered on by default.
Every module has NTSC quartz oscillator included
Example implementation in Amiga 500 was described HERE
This is fully assembled internal version.
Basic soldering skills are required.
Board requires six signals described as R, G, B, S, +5V, GND.
Please refer to your computers manual/schematics for exact soldering points.
+5V – Five Volt supply rail
GND – ground
R – RED
G – GREEN
B – BLUE
S – Sync
- NTSC quartz oscillator
This is a DIY KIT ! If you are not skilled enough to install it yourself then please do not buy it !
