RGB4ALL – Universal video converter v1.1

 

The RGB4ALL – video converter v1.1 is a universal converter based on the 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 successfully implemented it in the Atari ST series and in Sinclair ZX Spectrum 128k +2 or other hardware such as car audio/video stations.

Installing it in a machine with an NTSC circuitry is possible but requires a re-soldering quartz oscillator.

Please remember to change the SJ1 solder blob to the proper position if using NTSC mode.

There is a PAL quartz oscillator soldered on by default.

Every package has a spare NTSC quartz oscillator included.

 

UPDATE: Version 1.1 has S-Video and CHINCH sockets mounted on the top side for a more convenient installation.

I am offering a 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 computer manual/schematics for exact soldering points.

+5V    – Five Volt supply rail
GND  –  ground
R – RED
G – GREEN
B – BLUE
S – Sync

Package contains:

  • NTSC quartz oscillator
  • RGB4ALL

 

This is a DIY KIT! If you are not skilled enough to install it yourself then please do not buy it!
