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!
I have one question:
How does it check, how much RAM is in it?
Boot shows 128K, but the board has 512K
Incidentally there is a .zip file on Bitsavers called SageSources. Unpack it,
and in Sources1 look at PROM2.TXT. That is part of the 68000 source
for the boot ROM and contains the RAM test.
