Performa 550 Logic board

After a long wait, I finally picked this Lc550 logic board at the post office:

 

 

I got it at a good price from Japan, and now it will probably need some restoring.

 

 

 

It appears to be dirty but not too much, it even came with VRAM and RAM already installed. I’m just a bit concerned about the white dots surrounding some of the chips: should I toss it in the dishwasher? Advice needed.

 

Also, it came with this:

 

 

Since the logic board it’s going to be used in a Color Classic, I am considering of selling the backplate and cable if someone is interested.

It looks a bit like humidity damage - Japanese machines often aren’t stored in anything approaching a climate-controlled environment. Try brushing a bit of vinegar and then alcohol on there first and see if it goes away.

I might be interested in the backplate for my Performa 578, which I assume is identical?

Isn't the 578 identical to the 575? If so, I'm not sure the backplate will fit as it lacks the hole for the comm slot.

Nope, the port layout is different. The 575 models have one ADB port, 550 models two. So it won't fit.

Oh, well.  I had to try

 

Thanks !
