Item Description:
A RGB / CGA to VGA Converter PCB allows a 15KHz signal to display on a 31KHz PC VGA monitor, TFT monitor, or LCD display (either to 640x480 or 800x600). A great alternative to purchasing a expensive, heavy CGA monitor. Use this converter with an existing computer monitor or install a light-weight LCD display.
This converter has been pre-programmed to work via dipswitch settings for the following gaming PCB output types;
-Normal ICB CM99, Subsino
-CYE
-IGS
-Amatic
-Jolly Joker
-Witch Game
-Cuty Line
-Dyna X
-Psikyo
-Bigigo
-For Separate Sync

Features:
* RGB/CGA game board signal can display on PC monitor or TFT monitor.
* All new design for low picture noise and detects wider range in game board timing.
* Low-resolution enhance to Hi-resolution.
* Picture more sharpness and tiny pixel.
* Support sync-combine mode and sync-separate mode select by DIP SW
* Support CGA and VGA input select by VGA bypass SW.
* Support multi-game board select by 16ch DIP SW.
* RGB gain adjusts by 3 variable adjustment control pots.

Item includes:
1 - ACV-011 Model CGA to VGA Converter
1 - DC Power Connection (Connects to power supply +12VDC)
1 - RGB Cable
1 - Detailed Installation Sheet

Can it do 50Hz? Mebbies I could use it on my borked 1200 to fix the brightness issue? I see RGB gain adjust! How much does it cost? - DAMN - it would be cheaper to buy a new 1200 board :(

thought you were paying me a visit rabbit hehehehhehe

looks like this is the same thing except half the price...

I am - don't worry! Might not be when planned due to a screw up (not my fault - Its a BT / Other comms company cock up), I'll have to keep you posted.

None (or at least almost none) of these converters can do 50 Hz! :sad
Normal VGA frequencies have a vertical refresh >= 60 Hz.

Here is.. but not so good results,and not supported all vga monitor type.. :(
on Flatron LG 17" M1717A, and Viewsonic 19" E96f not working.. only on my Dell i take screen.
continue...

That doesn't look too too bad. Maybe if the cable was shielded it would improve the picture quality. Theres a lot of EMF that they could be picking up. Also if you have VGA input on your TV, try that and see if that is better. (I never buy Dell, either for me or for work :)

No is not has not stability and clear signal,for gaming is good for desktop not.
so.. im on trying to connect and others machines,like Spectrum +3,Atari STE,ect..
also i want to fix some flickers or low signal with caps ,resistors,or any..
any way, i have already this from ebay with 55 euro only.

This has an Averlogic AL250 which means you're limited to 16-bit colour :(

i.e. colour loss in AGA mode.

given indivision price, you shouldn't care about these....

These boards can be bought for a lot lower than $99!

We've seen them as low as $49.99 with an average about $65

Here is the my new solution..(i have rdy test also on my Atari STE and working good. ):D
important:
1.needed stable transformer 12V with 1+Amp
2. cooled the 2 chip

I have got a problem with sync. It looks like some black or red lines are blinking or move/shake. Any idea what can be wrong?

have you this converter?
you can test to connect the composite sync (Amiga pin 10) to pin 5 (H) on converter, whit out using the line 6 (V) vertical.

I will try this. Thanks

Hello Everybody

I'm new here, (sorry for my poor English)

I successfully tested this converter too, since many mouths now. Separated sync works fine but H+V, no.

My ACV-011 is 2 years old now, maybe the news ones integer good H+V sync timing for the Amiga ?

I will also receive a new converter soon, cheaper (about 30$) i will post result.

Regards,

Greg.
