malarkey? combo c64/3d & DCE: Flicker Magic

[DutchinUSA]

Ok, just a thought and don't bite my head off because of sounding stupid :nuts:

Does anyone know if the scan doubler input on the http://www.amiga-hardware.com/showhardware.cgi?HARDID=447 can be fed with the output from the http://www.amiga-hardware.com/showhardware.cgi?HARDID=361 ?

No. That gfx card doesn't have an input, it has 2 outputs.
The optional scandoubler module for the cybervision passes the rtg through.

I'm talking the internal connection though. The internal header on the 64/3d where you would normally connect the scan doubling module.

If you look at the picture close to where the external 15pin vga connector is there is a 10pin internal connector.

And from the Flicker Magic you can see where a 10pin ribbon connects to the 15pin vga connector.

I meant to take that 10pin ribbon and instead of hooking it up to the external 15pin vga connector hook it up to the input (10 pin connector) on the 64/3d.

I think normally externally you have a cable from 23pin rgb to input on the scan doubling module, module doubles the 15khz 23pin rgb signal and passes it to the 64/3d through that 10pin connector .. right?

If it's just a matter of passing the signal through (the 10pin on the 64/3d) then I would think theoretically you could do the same by using the Flicker Magic but not sure if the pinout would be the same?

Hope it makes more sense now what I am trying to say

probably,but i dont remember the pinouts for them though.

 

[DutchinUSA]

I should be able to figure those out with my multimeter I think

It would be neat if it would work since that scan doubler module seems pretty darn rare !

 

[roy_bates]

i think that eyetech did a very similar solution years ago and i think it was with the same hardware.

hook it up to the input (10 pin connector) on the 64/3d.

No, that is not an input. It's an output, the monitor switch is on the scandoubler, not the gfx card.

No, it takes the rgb from the video slot.

It made sense right from the beginning, but it still wont work.
Your assuming the Cybervision 64/3d has a built in monitor switch and passes through output from the scandoubler.
It's the other way around. The SCANDOUBLER has a built in monitor switch with and passes through output from the Cybervision rtg card.

Gotcha, guess I should have looked at the online manual first !

"Die zweite leere Buchse dient zum Aufnehmen des optional erhältlichen Scandoubler-Moduls. Das Scandoubler-Modul verdoppelt die Zeilenfrequenz des Amiga-Signals und ermöglicht so die Anzeige von Amiga spezifischen 15 KHz-Modi auf Ihrem VGA-Monitor. Haben Sie die Scandoubleroption installiert und nur einen VGA-Monitor im Betrieb so schließen Sie Ihren VGA-Monitor an diese Buchse an."

Thanks for clearing that up

 

[roy_bates]

you can still do it ,you just need an rtg switch.

 

[DutchinUSA]

Yeah, totally explains value of the Picasso IV also, add the other 3 up and umm yeah

 

[roy_bates]

i think you mis-understand you have a scandoubler(with vga out) you have a graphics card (again with vga out)you just need a switch on the two outputs to switch between them both, there are automatic vga switches.

like this:

No, I get it

Just trying not to use any price driving comments

 

[roy_bates]

ah ok

The Ratte switch is a very nice solution.
Maybe Kipper2k is worth contacting, I seem to recall him making a comment about modifying the switch specifically for the CV 64/3D so it worked without needing to load the software to run it.

If cost is a concern (when talking RTG and flicker fixers you most likely have already gone way over-budget already) you *may* be able to modify a more generic switch-box to work with the switching software.

Disclaimer: that's a very big may... will need to do more research. AFAIK The software detects a rtg screen mode and sends a signal to the parallel port... Maybe that signal could be used with another switch.

it can be done,ive done it with a voodoo 3 and a gbs 8200.and a generic vga switch box(the push button type)and converted it to full auto.


you just have to be carefull which switch box you get,because of electronic issues.(some use a different way of switching than others,with the same end result.)and require a different way of controlling it via a 5 volt control method.
