Hi Magnus,

I tried four different ET4000 cards in my NOVA interface last weekend. Only
one card of those four somehow worked. The NVDI-ET4000 was however unable to
detect the card, it looked like a lot of data was lost during the transfer.
At last I started REDIRECT.PRG (just simple program for setting up 640x400x2
resolution and redirecting ST videoram to the card). It showed the Atari
desktop, but the screen was partially messed up - it looked like some words
were shifted left or right a bit. Simply unusable... I believe that it was
thanks to that 'timing problems' Gerhard mentioned me many times (he said
NOVA Falcon got a Mach64 specific GAL)

>Also at what speed does your Falcon run on?

It was plain Falcon030/16 MHz

>Maybe you could make your own GAL. :-)

Well, it seems to be a solution ;-) Perhaps I could use NOVA for a network
card then :-) :((
