You don't remember what the picasso is for?
Are you sure you didn't pick this up from a garage sale and you're trying to find out if it's worth something ;-) ?
The Picasso is a retargetable graphics card which outputs at VGA frequencies. Your flickerfixer doubles the 15KHz screen up to VGA frequencies.
The p2 has a passthrough on it that automatically switches when it is in use: you should have a cable from the output of the flickerfixer into the p2, then connect your monitor to the P2.
Nice setup!
