Hi,
I just get a 520 STE in a poor condition. After cleaning and replacing PSU (the one that came with the ST was faulty), I tryed to start it up !
The screen appears, flashing, and after 10s, 2 bombs appear. I've read that this is "BUS error" !
I test many RAM swap (with some I had that I know are OK), same thing.
I've cleaned the PLCC/chips with deoxit ... same thing.
It's my first ST, I don't have any background with this machine, so if someone could give me some hints ...
Thank you in advance for your advices.
