This may be somewhat off-topic, but I figured I'd ask anyway.
I have an Amiga 1200 by Escom (from Amiga Magic German bundle, board revision 1D).
I have this disturbing hardware problem with the Amiga randomly GURUing and sometimes rebooting. This happens with no additional hardware installed, just the HDD.
Tried a couple different PSUs to no avail.
The problem can be almost certainly reproduced by soft-resetting the Amiga and getting to the configuration screen (with boot order and stuff) - and in the menus there, instead of names of boot devices - garbage appears, as if there's some memory corruption happening.
I know, that sounds very much like bad capacitors, but when I've de-soldered all the electrolytic ones, their capacitance measures within the margin of error from their stated value. Could they have still gone bad? I've already ordered a replacement kit, will see if it solves it.
What could be other causes for that? Bad RAM(is there a reliable way to test chip ram?), CPU cache, custom chips? Will my newly-ordered ACA1233n help me with that somehow?
