Since the 128 and 512 were same board when the 512 was introduced I would think so.

Should be , I have a donor 512 but have not found them since moving.

McD replaced my ram and it changed nothing then changed it back since it was the apple branded ram for me, which as a 128 is kinda cool for me.  I have 2 working 128's but both upg…

Too bad. I have a Simasima 1400, and it turns out that the 1400 is OK, its the LCD Screen that is Simasima. I would love to fix that one day. 

I looked at your pics (it did not load the first time I posted but that is on my end). Sad news. Looking at the bottom board, I saw several of the solder joints from the capacitor…

Just FYI my ram was swapped with new chips and no change. If you have video artifacts with the error code another chip may be at fault. I have yet to figure it out. Now that I a…

PB 1400c use Sharp LQ1142 11.3" screen. You can find some alone on the bay, but not cheap. Don't know in what other machine it's been used...
