Just wondering why clone Picasso II? There are much faster Graphics cards wich has schematics lying around, chips availlable and support for Zorro III.

As I have understand it is possible and actually very easy read chips data?

With a GD5434 it's merely a Piccolo clone, just a plain ZorroII version. And that's why something much faster has no use with ZorroII 3.5 MB/s max "speed" which isn't enough even for 640x480 at good fps.

That was excatly my point. Why to limit it to Zorro II? Why they choosed poor chip and support only for Zorro II?

Tseng Labs ET4000W32 offers some FPS more for Quake even with Zorro II bus, compared to Cirrus Logic GD5434. Easiest to found amiga supported chip is however S3 Virge.

There is no FPGA in that card, it has a real thing.
