Video Card for Amiga 600 possible?

[Whitesnake]

Now that you can add usb support to the Amiga 600 via Clockport and Subway i read up on usb Video Cards, Does anyone think it would be possible to make a setup like this work?
Or design a Video Card that could clip on Super Denise? :-)

AFAIK, video cards are USB 2.0 , so even if drivers were available they'd drop back to the lower speed of the Subway.

There is one method that might work.. hack a ZII slot onto a 630 accelerator card. It's possible without the 630, but it wouldn't be much fun with only 1mb and a 68000.

How do you mean hack it on :)? where?

[Doobrey]

Wherever you can get the signals you need :-o

It's been done on an A500, and seeing as the A600 isn't much more than a surface mount version of the A500 , I can't see any reason why it wouldnt work.
But, it'll be an ugly hack with wires everywhere cos the a600 doesnt have the side expansion slot of the A500 , and you'd never get the case closed again.

And what about http://www.amiga-hardware.com/showhardware.cgi?HARDID=498 :-? I know it is not really a gfx card but you can use it for Workbench enhancement, not ??? AND you can still buy them new !!! :lol:

[Piru]

you can use it for Workbench enhancement

How would you do that exactly?

[Doppie1200]

Yes this is possible. Mankind sends man to the moon so this is peanuts. What is your budget? I think you'll scare away if you find out what this will all cost. Assuming this is going to be designed by hobbists in spare time, you will not have to pay them by the hour. But you will need some prototype boards made.

Like being said already; design a board that clips over the 68k. You'll have access to the 24bit address space. There is 8MB fastram space free to use within the A600 architecture. But if you use more than 4MB you'll have to disable the PCMCIA somehow. If you are a really brave man you design a processor upgrade and use an 030. Then you'll have 32bit address space and map your expantions above $0FFFFFFF. Then you'll have to write some drivers and.......why am I telling you all this there is no way someone will attempt a venture on this scale.

Let the A600 be. Buy something better ;-)

One of my A600's has a very stange "video card" cliped over the Denise chip...

See Here (http://www.amiga-hardware.com/showhardware.cgi?HARDID=59)


I've still not been able to figure out what it does...

@bloodline

looks like a display enhancer/flicker fixer to me. Probably similar in architecture to the ICD flicker fixer unit for the a500 that plugs into the dip slot for Denise/Superdenise. Not really a graphics card in the rtg sense and an external ff/sd would do the same thing via the external rgb 23-pin connector.

My guess was a flicker fixer... but as I've also noted on Amiga-Hardware.com, the images on the Harddrive are not displayable on a stock A600, also the machine outputs to a genlock that connects to a standard TV... I really can't see the point in a flicker fixer being there :-(

It's an odd board... I really can't figure out what it does.

Sadly next to nothing supports the Graffiti card other than a handful of programs, Which is a shame because it is a nice simple upgrade.

@bloodline

From what you described about it displaying HAM is 640 x 480...........this tells me its either some sort of Dynamic HAM display card hardware......or simply an AGA compatible Card!

It's certainly not AGA compatible, the best it can do is HAM-6, but it can do that colour mode in any resolution.. which is a feature not present in the OCS or ECS chipsets.

Hasn`t someone started a thred here, that he will see if he can write an RTG-Driver for this card not to long ago ? What came of it ?

@bloodline
Sounds like one of those A500-graphiccards that used "true" 12bit for 4096 colours but for an A600? :-?
Strange indeed.
