This is a simple single transistor composite video buffer board with removable pre-wired cables. It can be used to add a composite video output to various games consoles and computers from the 1980s which have only UHF TV output.
I started making these on veroboard each time I did a composite video mod, but soon got sick, so designed a PCB version. That made things easier, but I was still sick of preparing the wires on the AV leads. This is an evolution of that original design, produced for me by TFW8b.com, which has all the cabling ready to go.
The AV output is on a 3.5mm 4 pole jack, which can be positioned in the case to provide an external AV port with removable 3.5mm jack to phono lead (supplied).
I have used this kit to modify the following systems
Atari 2600 (all versions) - blog post
Atari 5200 - blog post
Atari 7800 PAL - blog post
Atari 7800 NTSC - blog post
Atari 400 - blog post
Sega Master System II - blog post
It could also be used on systems where I used the basic version of this kit:
Binatone Superstar 'Programmable' TV Game - blog post
Binatone TV Master - blog post
Radofin tele-sports TV game - blog post
This is only suitable for systems which have a composite video signal available internally to be boosted by this board. Most PAL and NTSC devices with a RF modulator can be converted. Oddities such as the SECAM Atari 2600 which use a sort of S-Video to drive a modulator chip are unsuitable for conversion without additional circuitry.
The pinout of the internal connector is as follows:
The 3.5mm 4 pole jack to three phono plug lead supplied has three plugs on the end:
(the audio signals pass through the board and are wired to both connectors).
The kit includes:
None of the systems shown in the example photographs
Soldering and desoldering is required, as in most systems parts need to be removed to disable existing video output systems, or mixing of audio onto the composite video signal for UHF TV sets. Follow the guides above, or ask for further information if your system is not shown. May not be suitable for all systems.
