This is a recreation from original data of the small snap off PCB of the PicassoIV (PIV) Amiga RTG graphics card. I created this because often cards seem to be sold without this PCB and then the FlickerFixer/ScanDoubler of the card cannot be used.
This is a four layer PCB.

Questions
How big is the PIV FliFi Slot PCB?
It measures 124 × 21 mm and has 4 copper layers, 1.6 mm thick.
What parts does the PIV FliFi Slot use?
16 parts, built around the 74F378SC. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the PIV FliFi Slot KiCad files?
From the MastaTabs/PIVFliFiattach repository on GitHub, at the commit this page was made from: the board is PIV_FliFi_Slot.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the PIV FliFi Slot design in my own project?
Its repository states no licence, so its author keeps all rights: ask MastaTabs before reusing the design.
