Indivision AGA for the A1200?

[smerf]

Hi,

Anybody tried that 15khz rgb to VGA converter that they have listed on ebay for $92, would really like to know how it works before I spend cash on one.

Thanks

If its this one
http://www.ambery.com/rgbcgatovgac.html

it works good. Picture is not perfect, workbench has a tiny bit of ghosting, and black backgrounds have vertical lines if you look closely, but its perfectly usable, games look great and its cheap.

I hope they fix the problem with soft booting, it is really annoying when the screen just stays black :madashell:...

[arnljot]

Is this the hack that prevents the "flicker" at the top of the screen in hi-res modes that occurs for 5 - 10 minutes after booting (or until the machine is warm?)

Link?

TC, TheCorifot at AmiBay can tell you more about it.

On the A1200 he says:

You need to short out E127R which is on the underside of the A1200 Mobo in order to clean up the CLK signal.

Here

And then the A4000 version hack:

It's a 1K resistor between +5V and the CCK line which raises the peak to peak amplitude of the clock signal to over 4 Volts, Without it the signal swing is 3.4V

One just sold on ebay for about TWICE the original price.

I'm so tempted to sell mine, purely for the profit :razz:

I have this one http://www.ambery.com/rgbcgatovgac.html and it works great. No ghosting or artifacts and does PAL to NTSC conversion. The max. input resolution is PAL: High Res 640x256 or PAL: High Res Laced 640x512.

I also have this for HDMI connectivity, but it does not do PAL to NTSC conversion. It also works great, beautiful picture on 60" TV http://cgi.ebay.com/ws/eBayISAPI.dll...=STRK:MEWNX:IT
It does require a SCART cable that can also be purchased on eBay.

Comparing a 15kHz converter with the indivison aga is stupid.
Or can you do that ...

Maybe and maybe not. For workbench work you don't need any of the devices and just use one of the Productivity modes. For games it doesn't matter as they are low res anyway. For those who need PAL to NTSC conversion for games the 15kHz converter is actually pretty convenient, especially if you have additional 15kHz computers (ZX Spectrum, Atari, C64, etc). I'm not taking anything away from Indivision, but both products have its purpose.

For those of you wondering what the new Indivision will be like, this is what I heard back from Individual a day or two ago:

"A new version of the device is planned for Xmas business of this year. Even the old ones are compatible with the Rev.2B motherboard and HP Lisa chips. The only known unresolved issue we have is with Rev.1A boards. We just recently resolved an issue with Rev.1B boards and we have one of those Rev.1A boards on it's way to us, so we can make the new unit compatible with the whole range."

Also, I have that 15KHz adaptor from ebay you're talking about, and it does work ok, except for the vertical lines, and it has this big issue where it often puts the fields in the wrong order (interlaced modes only), and changing the screen mode back and forth fixes it half the time. It's a big pain.

[tom16mm]

Oh, that 15KHz adaptor also has some jagged artifacts in NTSC with vertical lines.

If anyone has any ideas on how to fix the adaptor issues, that would be wonderful. At least until I get an Indivision. I have the 15KHz adaptor connected directly to RGB, and the H and V sync pins.

I think there might be different versions/manufacturers of this adapter or maybe it's the same one just sold under many different brands. I have mine connected via this connector http://amigakit.leamancomputing.com/catalog/product_info.php?cPath=42&products_id=183 and the picture is crystal clear, no artifacts.

will it be the same revision as last time, or is there anything to the rumours that it´s a new revision with new features, not only mechanically but also feature wise?

I'm wishing to buy one at Versalia. Now they are out for holidays for some days, but this is what they told me:
 
Question:
"On Thursday 15 July 2010,...()... When do you think they will be for sale again? Do you have notices of Individual Computers about it?"
 
Answer:
"Hello,
 
There is no confirmed delivery date as of yet, we still hope for a release in
late summer.
 
But we've been told it's worth waiting for. "
 
I will buy to them, as I was asking Amikit to keep me informed the same week or one before they sold some of them, and they didn't tell me a word or a message... BTW the ones they sold were of course NOS.
