    John's Classic Restoration Thread

    Awesome! Glad to see it fully restored.
  2. Congrats! Glad you took another closer look at it. The line in the middle is indeed normal. It is the split point between the top and bottom half. Like I said above, the passive matrix displays are split in 2 to help with rendering.
  3. These two spots jump out at me.

    In total: missing components, cap goo, no ram. And of course, broken crt. It was obviously from that case. Salvaged parts off the corroded one and gave it a good wash. Haven’t tested inputs yet. The floppy drive didn’t work so I’ll have to tear into it and clean it.

    That was after washing the board. It worked for a couple minutes and then failed again and is doing what it did before. When it was working though, it chimed and everything. Even the sad Mac without rom or ram.

    SUCCESS!!! Well sort of... it has gone back to the state it was before, but it did work for a short few minutes!!

    Still have yet to figure this out.

    Perfect movie scene for this. I got super excited when the screen lit up in all its glory

    Alright so next update: it acts the same with or without ram/rom.

    I’m feeling great. I just transferred tiny parts over by hand

    FOUND OUR PROBLEM! thanks to reading the thread posted by @techknight I did some poking around and sure enough, L14 is completely missing! Gonna grab that off the other SE/30 board and see if I can get this one fired up. im also missing c74 and r35 (though r35 looks like it was never there to begin with). Hopefully they are still on the other board.

    Yes it’s missing quite a few components. Not too worried about that. After cleaning off most of the garbage the traces are actually not as bad as I expected. It’s still got a long way to go but it’s getting there. At the moment I actually have more hope for that board than the other one lol.

    An update: connected the speaker on both boards. The corroded nasty one made a sort of noise when powered on (no chime, no ram). The gold socketed one was silent.
