Correct me if I'm wrong but doesn't the EC chip lack an MMU like the '040 – and therefore would be of no use in a Mac?

From what I understand, this would be dangerous. I think the battery charge side of the original PSU is intentionally limited to 1A.

Will the gerbers be made available for this adapter once testing is complete?

Affirmative.

You'd still need the correct display flex cable and that's not going to be easy to come by.

Aren't there many second hand parts in Australia? I do appreciate it must make things more difficult. The good thing is that a RAM card is not very big or heavy, so postage shouldn't be ridiculous.

Just try to pick up a 4MB RAM card for 160-180c that's tested and working. It shouldn't cost very much - maybe $50 of your Australian dollars if you keep an eye open.

No, they won't. The 210 uses DRAM, the 1x0 uses PSRAM. You can get the needed chips from the models I listed.

PB 140/145/170 chips are too slow - those are 100ns whilst you need 85ns or faster. You can grab the chips from any PB160/165/165c/180/180c or RAM cards designed for them.

Is there a black market for failed MDD PSUs haha

Sharing my Mouser cart here. Diagram attached.

I can’t provide you with safety instructions sorry youre on your own But I can share a mouser cart with the parts needed if you want

I would recap the PSU as a matter of course. They are extremely unreliable in this model.

Well it depends, the board is likely repairable but if you can’t do or don’t otherwise have access to the SMD rework required then your only option is to replace it with a working component. Maybe donate it to someone else local who can repair it rather than throwing it away?

That won’t get you anywhere. You need to desolder chips and test them off board. Not easy or practical unless you’re equipped to do so.

Almost certainly a failed RAM chip on the CPU daughter card. Unless you’re able to identify the chip and solder in a replacement, you’ll be looking for another daughter card.

You could maybe get an ultra wide (68 pin) scsi drive off eBay. There are plenty of them. If you do, make sure to get a 68 pin cable with terminator built in plus a 68-50 pin adapter for the logic board. The adapters that you can buy that fit on the drives themselves are no good as they lack...

Oh wow. I’ve managed to save about 7
