    The 20 bucks SE/30 horror show?

    Ok, so not working BUT a great deal for the $$$! My parts board is in way worse shape.

    Color classic stopped working :(

    Help! I've been working on getting a color classic running for a bit. Thanks to @jajan547 I got a set of working ROMs that got the board up and running long enough to install a hard drive and System 7.5. The whole thing started and shutdown when told to several times, and the only thing not...

    Building an internal grayscale card for the SE/30

    Wow! A very interesting card. Going to have to keep a close eye on the forum for any 'open to order' type thread.

    Macintosh SE/30 logicboard recreation (thread revival)

    These days, that could be a trick question but given the clock frequencies of these older machines . . . Way back when, before the time of the Macintosh, back when people looked confused when you said you had a home computer, I built an Apple II clone and used a logic probe to determine if a...

    Color Classic no longer recognizes floppy driive

    Have you got a head cleaning disk? I got those kind of errors on my Apple II+ floppydrive and cleaning the heads fixed it (for now at least . . .).

    Macintosh SE/30 logicboard recreation (thread revival)

    I can't answer the RAM bank question as I don't have a reloaded board but I would assume they are, hopefully Bolle can chime in. I would think the CPU, ROMs, and some RAM for video would be the minimum for any 'kind of proof of life' (based on other computers I've worked on). If the caps you're...

    Hey - CayMac on YouTube has a stream up on his Reloaded build, and he's into the troubleshooting part of the build.

    Macintosh SE/30 logicboard recreation (thread revival)

    Excellent! I don't have SE/30 schematics, but take a look at the solder joints / continuity of the ROM v.s. the SIMM sockets. I would think the connectivity of the two methods is the same (or pick up another 64 Pin SIMM and call it a day). Does the reset occur when the reset line is held high...

    Macintosh SE/30 logicboard recreation (thread revival)

    Check that any parts with polarity are in the correct way around and there are no solder bridges. Then check the voltage supplies and ground rails to make sure they are working as expected. If all that checks out OK, I'd move on to checking that the clock signal on all the chips is working /...

    SE/30 White Screen

    I'm no expert, but anytime I see CRT issues I immediately think the analog board needs to be looked at.

    Macintosh SE/30 logicboard recreation (thread revival)

    I'd be interested in one of your extra boards, if you have any that are unspoken for.
