Title: Using A3000's internal SD/FF with CV64/3D
Post by: McVenco on September 14, 2007, 08:57:13 PM
I a short while I will receive my A3000 which I bought from a very friendly German guy, and I plan to put in my Cybervision 64/3D in that machine. Now is my question: can I use the internal SD/FF from the A3k in combination with that card, and if so: how? What should I connect where, or do I just plug in a TFT monitor to the 31kHz output on the back of the A3k?

Somebody enlighten me in this matter please...

You get two separate outputs with the CV643D card, one CGFX output from the card, and the other from SS/FF from A3000 since the CV643d do not have automatic videoswitcher. CV643d was designed to only work with the scandoubler module.

As CV643D states.
The monitor switcher is part of the scandoubler module, not the CV643D board.

Are there any other RTG cards which WILL work with the onboard SD/FF from the A3k, or do they all need a separate SD/FF? In short: does the onboard 31 kHz output work only with the Amiga native modes?

What you're looking for is a graphics card with a passthrough connector. You simply plug the A3000 output to this connector and the card performs automatic switching. The CV64 has this, also picasso2s, Spectrums and many others I believe.

I'm not getting what exactly you're looking for - some RTG cards (my Merlin for instance) have a video input and an integrated switcher, so that when a native screen is up front, the card passes the input to its output, thus showing native video. In combination with a FF you can use a 31kHz+ monitor for everything. Without a FF you'd need a 15-31kHz+ multiscan monitor.

The CV64 doesn't have a VGA style input, but it sits in the video slot and deinterlaces the native signal on its own, so you won't need the A3k 31kHz output.

If that answers your question.

Nopes, CV64 doesn't have scandoubler. It just has a passthrough port, and thus doesn't sit on the video port. CV64/3d has an optional scandoubler module, but he doesn't need it with an A3000 like you said (probably he doesn't have it anyway).

@countzero

You did read the initial post ?  Or even just the topic-line ?


Thought so  ;-)

Back to topic:

The CV64_3D comes with it's own solution to the 15kHz prob, and therefore won't work with normal FF/SD.

Other cards have a passthrough (most of the times another VGA-Style connector), and you have to mega sure that whats going in there is suitable for the monitor, no matter wether the source is a FF (built in or an card), SD, pure AGA or even  a completly different computer.
