we live as we dream. Alone.
I'm sure most of you have read Harrison's thread in this cheap and cheerful Chinese rgb adator on EBay.
If not have a quick read on Harrison's thread and check out eBay.
Now my version is the single output 8200 rgb to VGA, the new version has dual VGA output but uses the same board.
This CGA/EGA/YUV to VGA Arcade Converter PCB allows all types of RGB, EGA, VGA or YUV component signals to be up-converter and display on a 31KHz PC VGA monitor, TFT monitor, LCD display, or HD-TV with VGA connection. No need to set dip switches in order to figure out the specific input frequency as all inputs are detected automatically.
Supports CGA/EGA/VGA/YUV Component Signal Input
Supports VGA Output (640 x 480, 800 x 600, 1024 x 768, 1360 x 768)
CGA/EGA/VGA signal auto scan (15KHz, 24KHz, 31KHz)
YUV Component signal auto scan (480i, 576i, 720i, 1080i, 480p, 576p, 720p, 1080p)
On Screen Display (English and Chinese)
Supports image position control & image zoom control
True digital 24-bit A/D converter for true 16.7-million color conversion.
Supports ALL types of VGA monitors (CRT, LCD, PDP, Projector, etc)

On the Amiga.
The first thing you need to do is wire the thing up, you have to wire up an rgb 23 pin socket from the Amiga ( for native screens I.e whdload games ) to the VGA adaptor - its not hard and supprisinly few wires are connected.
The Amiga screen output is then magically converted into a VGA output to your LCD tv / monitor or even back in to the Amiga for an rtg card input ( Picasso 2 and others )
So wiring done , power?
Some people have wired this to the rgb socket and used the power from that, others use a small psu. I have tried both.
Results / use ?
Personally I use 1024x768 and English menus of course , I haven't played with any other setting apart from cropping the screen size to suit my Samsung tv.
The results are generally good , the picture is mostly stable but I have some wobble at the bottom of the screen that is constant no matter how I size the picture and I also have some ghosting on the mouse pointer , seemingly in a square area around the pointer - no matter where on screen.
Does any of this matter ?
No not really it means I can pass through and auto switch from VGA Picasso to VGA native Amiga without me doing anything. Joy
Overall?
It's cheap , you need to make an rgb lead and buy a psu or power from the rgb. So do I recommend it. Yes I do but if something else came along and offered a similar price but more stable picture, I would buy that.
I have yet to try it on another tv and with another Amiga but I briefly tried it on a 500 and its just as happy to display.
