Hi Petr!
Will the 68LC030 still be useable somehow when the AB040 is plugged in?
Is there a jumper or a switch?

When you look at the circuit diagrams you might understand a bit.
Will you come to Oldenburg this year? I can bring my oscilloscope.

What brings Nemesis with the AB040??

Can you find out at which physical address of the FastRAM? I had
expected it at 0x01000000. In the Medusa already it is at 0x24000000 or
something depending on the population of the 2 Banks.

Isn't the AB040 designed by Gero Anschuetz, the guy who also built the
Eagle 030 TT-clone?.... Are there ACTEL chips on the AB040? Can one
still buy the AB040 new?
BTW: What does your NOVA say so far? Did mach64fb.c work for you? (not
atyfb)
