I'm working on a Mac Classic. I recapped the motherboard and it boots and works fine. However, I noticed that the screen image has a weird subtle shake/wobble to it. I haven't seen this sort of thing before, I attached a video clip that illustrates it (watching the menubar is the easiest way to...

Thankfully the software ended up getting captured by the Internet Archive: https://web.archive.org/web/20080511123533/http://daystartechnology.com/Daystar_Technology_Mac_Support/Daystar_Technology_Mac_Downloads/Daystar_Digital_Mac_Downloads/software/b_dsd_software_download1.html

I'll try to take a crack at these: 1. Shapeways is probably the best-known, but there are plenty of other print-on-demand services out there. Both PCBWay and JLCPCB offer 3D print-on-demand services. Hubs is another one, and before I bought my own printer, I used a previous incarnation of it...

I've had good luck using magic erasers on Mac cases for scuff marks, as long as you don't go crazy with it there won't be any affect on the plastic's texture.

That's correct -- the only compact Mac with soft power is the Color Classic series.

No shorts on any of the pins -- I examined them all under the microscope. Dark spots are just some flux residue, which I've cleaned up. Looks like it might be a little tarnished, but nothing connects to it (or the pin header next to the card edge connector) from the system. I think it's...

So here's a super mahoosive photo of the card without the heatsink. The shiny parts around the CPU legs are flux residue, not solder bridges -- I inspected the card under the microscope for those. I also recapped the motherboard just to get that out of the way, and there's no change. It still...

CA glue is probably fine (and certainly a lot easier to obtain) but if you want a more "official" SMD component glue, something like Loctite 3609 is what gets used to secure parts to PCBs before they go through reflow during manufacturing.

I'll see what I can do -- but I'm starting to suspect the motherboard. I dug out the dual-CPU card from my 9500 and while the machine boots with it installed, the DayStar utility reports that one of the CPUs isn't working. That *could* just be a software thing, but it's a bit peculiar nonetheless.

I have a DayStar Genesis MP with the quad CPU card, and it doesn't want to boot. Pressing the power button gets the system to power on, but there's no chime, video, or hard drive activity. The system has a brand new PRAM battery. Swapping the CPU card for another one, like a Sonnet G3...

Sounds like cracked solder joints on the analog board -- a common problem with that model. As the machine heats up, the components expand slightly and eventually make connection.

Here's my entry.

This is an interesting tidbit to learn -- I always assumed that the motherboard did some advanced ROM-level trickery to present a different SCSI ID to the host Mac than what the internal drive is set to. It's maybe even more clever that the motherboard simply changes the actual ID of the drive...

Having done several standoff replacements, I'm confident in the strength of brass inserts that have been melted into FDM parts. I have no basis for comparison of the strength of FDM vs SLA parts themselves in this application, though -- my gut tells me it probably doesn't matter.

I can't say I've ever seen that before, but given the part number on the PCB and the quality of the wiring, I'd actually suspect this is a factory bodge.

Thanks, I'll let you know if I need it -- I've managed to secure a donor board, but I haven't received it so I don't know its condition quite yet.

Yeah, that was the main reason why I decided to recap the board...but those traces really all did look fine. This board definitely wasn't a battery bomb victim, and I'm starting to suspect its original factory caps hadn't really even started leaking. The known-good board from my other Color...

First thing that comes to mind is potentially a voltage issue. Perhaps try using the PSU from your known-good machine with the problematic board, if you haven't already?

I swapped the ROM chips with my known-good CC board, no change. The originals (and the ones I swapped in) were seated just like the ones in your photo.
