Title: Picasso IV on an Amiga 500?
Post by: Miked on July 02, 2006, 07:58:19 AM
I know there were other threads about graphics card, but I was wondering if anyone had any idea if this is possible?  Of course, the flicker fixer wouldn't be able to be hooked up, and it would be in a zorro II slot..but is this set up worth the trouble?  Theories are appreciated :)

It should be possible.

You can also do an A2000 video slot, the signals are available from the motherboard / Denise pins.

If you don't have at least an 030 A500, don't bother.

There is a special adapter for Denise and the PIV you could use to get the Amiga video signals into the PIV.

@MastaTabs:
could you provide more info about that adaptor? I have a desktop A4000 with mediator with no videoslot and I may like to use it as FlickerFixer.

The A4000 doesnt have a Denise chip and so any A500 adapter would be useless.

If you have an A4000 you *SHOULD* be able to use any of the numerous internal A1200 Scandoubler / flicker fixer solutions which clip over the Lisa chip

I've been searching for information on creating a video slot but have been unable to find anything.  Anyone have any documentation? (Of course the Denise adapter for the P IV would be a great solution but that would be almost as impossible as finding the PIV board itself - anyone know where to get one of these denise adapters?)

@Grumb

Most signals of the A2000/3000 videoslot are available on the RGB connector (it may be a bit different for the A4000 videoslot).

But there is allways another chance.

I assume you have the desktop-version ? As the A4000Dintower-version does have a video-slot.


You might use the orginal Daughterboard to trace the signals from the video-slot to the connector on the mobo.

Now find those contacts on the Mediator and you got a start.

Google for the A500 schematics, then the A2000 video slot pinout and the A500 RGB connector pinout.

Then it's a matter of soldering the correct signals to the correct pins. :-)

Check the PIV's flifi part if you can see what signals exactly the PIV uses, that'll save you some soldering.

Thanks for the good advice.

Just on a side note- were any drivers/software ever made for the PIV that allowed for dragable windows?  Did the Cybervision 64/3D support dragable windows?

Do you mean  draggable screens?

CGX supports them, but if you turn it on, switching screens becomes slower.

I've actually learned to live without draggable screens nowadays - I usually run a mixed set of RTG and custom chip screens anyway, so I can't make full use of it anyway.
