Hello everyone
So I have this Macintosh Performa 200 I bought few days ago.
When I got home I tried it out and it had some vertical bars and the PSU has issues.
So I recapped the PSU and changed the opto coupler and it's sorted the PSU.
But the motherboard is full of problems!.
I recaped the whole board and repaired traces that might be wonky and even tried desoldering and resoldering the CPU,MMU,RAM and Ergat chip with the hot air station
Also tried soldering new RAM chips and no change
I've looked for bad traces and can't find anything that looks suspicious .
When I boot it it bongs then it throws the error sound and I get nothing else besides the bar screen shown in the photo!.
Can someone help me out getting this beast up and running or can someone sell me a Classic II board that I can use in this Mac?
It's in really really good condition and it would be a shame to go to the dump or to be kept in my garage unused.
Thanks in advance!
