Title: Picasso IV missing flicker fixer module
Post by: Cirion on February 26, 2018, 11:33:05 AM

I just aquired a PicassoIV, and it has no flicker fixer module. The part was probably cut out for use in a A2000 and forgotten. The seller never had this part and he had bought the A4000T with this card like this.

At least the PicasoIV works as a RTG board.

Anyone know where I can buy the flixerfixer and the 2 ribbon cables?

That is really bad luck for you. Good luck, i think it is not easy to find the flicker fixer.

Perhaps you can buy a separate flicker fixer.

Probably could be hacked - the FliFi is on the main board afaik, the break out is just for connections.

Here are the necessary schematics (http://www.sophisticated-development.de/software/getfile.php?file=.//P-IV/PicassoIV-schematic.pdf)

Doesn't there also exist an adapter that sits underneath Denise?  Might be easier to fabricate your own one of those, as opposed to fab'ing a PCB and pin headers to fit in the video slot.

Or I suppose an Indivision ECS would also work, provided you can find the proper pinouts and the signal is compatible.  Personally I've had good success running an Indi ECS through a GVP Spectrum, but could never get it to work right going through the switcher on a Picasso II.  But YMMV.  Good luck!  :)

Yes, it did, made by Village Tronic. Was for A2000 and A500 towers. I have one in my A500T - works fine.
