This is the current state of my repair attempt. And now I have to wait for the ordered parts...

@trebroNdotnet Do you know if the A3000 Kickstart can boot with no fast RAM at all?
I'm trying to debug why I'm no longer getting a red screen: https://mstdn.io/@codewiz/113642654942378778
@codewiz There are A3000 with early Kickstarts softloading the Kickstartfile to FastMEM. All other A3000 should work with just ChipMEM.
@trebroNdotnet All right, something seems to be busted on the fast ram bus.
I tried moving the socketed chip RAM chips to the DIP sockets and flip the dip switch to 256x4, but the DiagROM mem test is still failing. Since it's all 32 bits, it might be something with the address bus, or maybe the bridge logic.
@codewiz Not shure if you have seen my replay https://mastodon.social/@trebroNdotnet/113622475660805537 -> marked some areas with corroded/mangled traces. Theres no shortpath in restoring a battery damaged computer:-)
