  1. There isn’t much else to explain except that literally nothing happens when powered on. I know the analog board and crt are good because I tested it with another board. Picture of the board can be seen below. Where do I start? I’m sure even if the caps were bad it would do *something*

    SE/30 nothing happens when powered on

    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.

    Reviving a Macintosh Plus.

    Got this one from Johnnya101. Had only a vertical line on the screen. I snapped the connector on the red wire so I had to replace that... the rest was pretty straightforward. Just used a solder-sucker and got rid of the old stuff around the problem areas and re-soldered.

    Reviving a Macintosh Plus.

    I’m kicking myself for not leaving 2 out to test the SE/30s! These are a pain to get in to.

    Yea I think that would be my next step. Oh by the way @Johnnya101, that floppy connector housing didn’t last long lol. I think I could’ve peeled it off with my bare hands. One of the screws snapped while removing it but oh well. To confirm, nothing happens at all. It’s rather strange. I’m surprised that my ultra-corroded board had more success.... it even displayed something on the screen!

    WOAH! Already a massive improvement. Keep it up!

    Glad that thing is getting retrobrite. I agree it was quite intensely yellow. Would you believe me if I said my Plus was worse im surprised at how much dust accumulated. I cleaned that thing inside quite extensively (with a dry toothbrush and damp paper towel). My partial disassembly can be seen here: the 68k also happens to be my profile pic.

    128k Macintosh board is it worth much?

    How much is shipping to the US? That would help a lot of the users here. There are definitely people over on your end who would like it too though. Don't scrap it!

    Woah. This is exactly the sort of setup I’ve got my eye out for. Clean setup!

    Figured I should make a proper thread for the future of my conquests. Got some items today in the mail.

    Yea I’m thinking of heading up to Grafton sometime soon so I would be in the area. Just let me know your asking price and we can talk

    Are you by any chance interested in getting rid of one of the pluses. I might like another one... for a project.

    2011 iMac

    Not sure how I end up with such nice items for free. Some friends were getting rid of it and knew that I collected such things, but man I've been using it as my daily machine now! Upgrade to 8gb and a nice SSD and it should last a few more years.

    2011 iMac

    SSD and ram upgrades are surely a must. Is there anything that can be done to prolong the life of the OEM graphics chip? Is it integrated or in a slot (what slot)?
