Really appreciate all your help folks. Will report back with any further testing. Thank you! :)

Pulled that resistor, it was showing as a 10ohm right enough. Replaced it whilst it was out. Several of the caps were well past their best, showing signs of leakage/swelling etc. All were replaced along with the filter caps. PSU now soft starts with the jumper. Put the psu back in the machine...

Can’t thank you enough. Def think it’s brown black black gold. Will take mine out and confirm if it’s 10 ohm and likely replace it regardless.

That def looks red to me also. Any chance you can see what R322 is, mine looks a tad toasty here. Might swap it if I can work out what it is. Found this site which has some images, but still hard to see. https://oldcrap.org/2019/09/01/apple-macintosh-iicx/

Ah! I seen brown green yellow. Thank you.

Yikes, should I reinstall it? 150k ohm?

Also noticed this resistor has been snipped? Assuming it’s a factory thing as there’s no remnants inside? Can’t imagine it’s vapourised!

Will def do that if I can get it going. Had a chance this morning to test for trickle, showing 5v, joining to pfw fails to start the psu. Can confirm the fuses are fine and power is getting around the mains side of the board. Kinda grubby inside and can see a couple bulging caps along with the...

Cheers, will test this in the morning before i attempt recapping. Have seen the +5v continuous and the pfw pins, thanks for confirming it should be safe to bridge. Hopefully can sort it as its a great wee machine. Will report back.

Hi, The rifa's went in my IIcx astec power supply, machine is now totally dead, wont turn on. Have ordered the replacement caps and wondered if there was a safe way to start the psu on the bench for testing of output voltages much like how you would start an atx one. Have ordered the full set...

Hi, I have various 68k machines and I have always backed thing up by dragging and dropping. I have a piscsi nowadays and can create drives on the fly. What would be the best way to create a blessed image of my mac drives for archive purposes? Just piscsi into external scsi, create new drive...

I got a chance to check this tonight. The red line highlighted is still connected but the trace heading from the via is clearly broken. Currently deciding on whether to run some kynar wire or repair the trace under the chip. Obv still don’t know why this chip was lifted so thinking of...

Awesome, really appreciate this info. Will check this out later when I get home. Hopefully can fix some of this bodgery. Still no idea why this chip was being lifted, does the vram tend to fail?

Alright folks! I bought an se/30 board which I thought was alright, no battery damage, caps looked replaced etc. But on closer inspection the caps were installed very badly, some missing and electrolyte still on the board. The biggest issue was that one of the vram chips was half removed from...

That’s a great tip for opening the cases, I’ll be sure to give that a go! Having a hard time finding a 7.5v 3a psu. Any ones I find just seem cheap...
