Ah yes man thank you soooo much. Apparently there was a slightly bent pin in the plcc for agnus that I didn't notice before. So far I only checked for continuity from the top of the plcc pin to the other ICs (and perhaps actually bent the pin in the process
). But after bending all pins straight again the A2000 is back up and running again ^^
Interestingly enough I didn't notice any missing data on the bus where the bad connection was, probably due to activity from the connected ICs or cross-coupling.
Now I have to think what upgrades to do to the thing to make it most useful for me. I already have a harddisk and am thinking about doing one of the HDMI output mods. Any suggestions on other things I could do?
