Can you point me to where you read about the timings? That's =

No, I haven't but I will :)

Sounds nice.  I've seen some devices with a ARM at 56MHz =

inside. That's why I think a 33F could be enough for a VGA =

at 320x200 but Im just guessing.  For true color may be a =

FPGA is a more suitable device.
