Oh!

It’s boned.

Would you be able to share the top side as well?

Nice one, @s_pupp and that's definitely a stock 166MHz board (not a modified 133?)

Good work and you deserve a rest after that!

How do I get into OF from another machine without a serial port on the MDD? Or is there a way to save OF output to disk?

Yes, my card has S-Video out. My switch doesn’t have any silkscreen labelling to indicate what the switch does. But the photo of an R9000 from the Mac Elite does: Looks like the lower switch is PAL/NTSC, while the upper switch is the Mac/PC toggle. Not sure what SF and MF stand for but I...

Here’s my card with that switch desoldered for comparison. The via indicated with an arrow seems to go to the shared pad between R229 and R230. Even without removing my heatsink you can just see how my resistors are set up.

Does anyone have a high-res photo or scan of the underside of the MDD board (166MHz, FW400)?

I figure I should check to see if my flyback is arcing as well…

A lot has been done on these forums but there are still many projects left for the taking, which is a good thing. You could be that talented member!

Just pick off or cut the green stuff (as you did) and the tan stuff. The blue and brown wires will need to be desoldered from the PCB unfortunately.

That would suggest there is some other difference between a stock 133 and stock 166 board. Perhaps there is another option resistor that needs to be set (voltage?), or maybe the bill of materials is different and there is a chip inline with the memory controller that's rated to a slower speed.

I've installed a Dual 1GHz CPU in my MDD (formerly Dual 867), and bumped the bus speed to 166MHz by removing R676 on the underside of the logic board. However, it now has RAM-related issues with stability that it didn't have before. Depending on configuration, it either fails to boot or kernels...

I’m not sure if the soft power circuit will function without caps, so you might not get it to start. You could always try booting it and see. I’d probably try to be patient and just wait for the caps to arrive though.
