A520 & AGA?
« on: September 26, 2005, 04:10:02 AM »
Will the A520 modulator work in AGA modes from an A4000?

A4000D, A3640 OC-36.3MHz, custom tower, Mediator A4000D. Diamond Banshee 16M, Indivision AGA 4000, GVP HC+8.

Mac Mini 1.5GHz, that might run MorphOS someday, when the fools who own it come to the realization that 30 minutes just isn\'t enough time to play with it enough to decide whether or not you like it enough to cough up $200.

 - Someone please design SOME kind of DIY accelerator for the A4000. :D -

The A520 was designed for the OCS/ECS standard. But try it out anyway, who knows it might work?

I'm wondering because I've seen an S-Video hack for the A520... Which would be an awesome way to pump my A4k video into my PC, which has a Pinnacle video capture card in it.

It should work fine. But if you switch to a weirdassed VGA type mode, the output will be wacked.

If you're bound for S-Video, better look for a decent genlock at eBay - much better picture than a (hacked) 520 & same price.

I agree with Zac67. Get a Lola2000 if you can...I saw one a few months ago sell for £5 on Ebay!!

@Dr_Righteous

You can hack A1200 native composite output for S-Video, so I guess it should be possible for A4000 aswell (at least if the A4000 composite output uses this Sony chip...).


(Image from the FAUG magazine article by Tero Siironen .)
"naarasliitin edestä" == "female connector, front"
"maa" == "ground"


[EDIT]Oh well, this would be a nice hack, if only A4000 had composite output. Too bad.[/EDIT]

the A520 is a simple RGB>CVBS/RF encoder and works with ALL the Amiga
RGB port (less the model that doesn't feeds one of the power lines).

Is still a crap solution but with that hack, you can see the difference (see the wafeform on Dave's page)

Exactly, and this is in fact the only thing I miss from my A1200 :-(

Well, that kind of ruins the plan. Doh.

Again one reason why A1200 rules over A4000. :-)

by the way, you always could use the svideo output of a gfx card (most gfx as voodoos had one).
Do you have a gfx card?

Of course... I have a wonderful Voodoo3 PCI card. No PCI to put it on tho. But that kinda defeats the purpose anyway. Since SD/FF's are virtually non-existant for AGA, and those that do exist virtually impossible to find, I just want some way of replacing my aging C=1950 monitor, and viewing native graphics modes.

@Zac67 & X-ray

You know, now that I've seen the A520 mod page again, I think the Genlock idea is a more attractive one.
