Nice score. I was fortunate enough to acquire my 128k before SJ passed and prices skyrocketed. The power board needed the transformer replaced, but I managed to find a complete power board that was fully functional cheap but then when I put that in and powered it up I got a sad Mac and error code indicating a faulty RAM chip on the board. I've pulled the 128k board and replaced it with a 512k board until I can find a place where I can get a replacement RAM chip that won't make me buy 100 of them to fill their minimum order requirement. I considered salvaging one off of a broken 128k board but that's even an expensive proposition just to get one RAM chip with the number of people who bid for them whenever they become available whether they work or not. I haven't seen a broken one go for less than $60 or a working one for less than $125 for a long time, and I'm talking about the first design motherboard not the redesigned one that was shared with the 512k.

Well if you have two bad 128k boards, it makes sense to make one working! Especially if the RAM is Apple logo stamped. I think you can still get RAM chips from Digikey, but no logo or minimum order. Keep an eye out for original 128k boards, while prices are all over I did see three sell for around $100 in the past month. Its really hit or miss. I had to buy this Mac to finally get an unmolested board. And it was a gamble, I did not know if it would have been upgraded or not. Luckily it was not. In fact, I am pretty sure I have been the first person inside since it was made. Good luck with your search. Or like I said, if you have two original boards and both are not working right - make one good one. I bet you can still sell the canabalized one on eBay for a small amount anyway.
