Thanks!
It looks like you are right, playing a little with the RAM banks,
finally got me errors, so at least one chip is dead.
Will take few days, until my replacements arrive, but now I
have 384k of RAM ;-)

Still crashes, but we will see. The original sockets on the board are 
cheap, sometimes it feels that the chips are barely hanging in there :(

Cheers!
