I'm tryingg to do the same on my mac SE with 6.0.8, but it's impossible to drag something onto the system (suitcase) file/folder. Strange because (if i well remember) I already did it in my portable and i could set another keyboard layout that way, in the mac SE I cannot. weird.

I assume the caps kit sold by console5 has the correct size of caps…

Ok thanks.

A question about recap: tantalum or cans? Wich are the easiest so solder? This is my only concern. I do not care if they will last just 40 years and not 140… Thanks for your help on this

And what about those big pads? What are intended for? Shall I put some new solder on them?

Ok… rewiring cpu-rom pins is done. Shall I give a try, still with old caps, or better not to?

Looking at the board, do you think that once that ROM-CPU connections will be done the Mac would work again? what about that green corrosion on some chips? terrible or what?

yes, but seem worst on pictures. Most of what you see is a surface layer of what remains from the battery leak, which I can't remove even with IPA. When wet, you can clearly see the intact connections, but not all of them will be intact.

I posted some pics, by the way I live in Lugano.

Well I never recap anything, hope is not too difficult... seem that someone already work on that board, the battery was not the original one and i see some corrosion on that area, not too bad in my opinion but I actually cannot judge. maybe some more expert than me can tell better than me

here is ma board

Ok, I did some research and I found out that some connections between the ROM and the CPU are broken. According to the scheme I posted below I find out that 5 traces are broken (D0, D10, D9, A12, A18). But the ones on the glue chip are all good, at least the ones the guy who did this research...

Hello everyone, I found a Macintosh SE/30, removed the motherboard, cleaned it, and then tried to turn it on. Here is the result. Can any experts diagnose, or at least isolate, the problem from this symptom? I have read various things about simasimac, but it seems to be a different pattern...

I'm not such an espert... can you show me which is the driver?

I have already detached the panel and cleaned both sides of the board with IPA and a brush. The only thing I noticed was some corrosion in the ribbon welds, but I don't think that could be the cause of the problem. Looking at it, the board doesn't look too bad
