Hello:) (autocorrect made this: “Help”, probably a better way to start 😬)
Replaced LS166 and LS161 and the result went bad:(
Hope anybody can give some hints where we are going wrong here =)
Interesting topic. Is there a list of bodge wires/modifications for the 128-Plus analog boards? I have some with a resistor at the backside, some with a resistor on a transistor.. Love to know what is the function
Does anybody dare to classify these as original or fake??

I always am cautious from ordering from China, as a fact i don't do it at all normally but this one i cannot find anywhere
Cool insight, thanks.
I found this nice piece of information in Macintosh Repair & Upgrade secrets
And after googling a lot 128k logic boards and their images, i found that some of them have, and some of them don't - also early ones like week 6 can have it all the way up until week 43, only...
Hello again :)
We also removed a resistor pack at the 6522
I thought this was for a ram upgrade but now I think Its probably original
Does anybody know if it should be there and Why? I Cannot find anything about it
hello all, we just finished replacing the ram chips on this board, did not boot, sad mac
Now we have these, what I know as jail bars like my se 30 Had =)
Anybody got some hints where to look first?
Sorry, i was not clear but its the logic board that causes the fuse to pop on the analog board
Other Logic boards go juuust fine :)
I have recapped and fresh analog boards and they work great
Thanks!!
