I have a IIci that powers-up a moment after it's connected to power. It boots normally but when it' supposed to shutdown, it reboots. What I have done so far: - recapped logic board - recapped PSU - checked each cap for continuity and correct polarity/capacitance/voltage - measured voltages on...

I just got an unopened kit of the "Micro Courier" for Apple ///. Unfortunately, the two floppy disks seem to have issues, so I can't start the program. Two questions: - Does anyone have disk images of "Micro Courier"? - Which program would you recommend to fix defective floppy disks...

Does anyone have a link to this file? VIMAGEPCCARD11.sit.hqx - I believe it's for this PC Card: I noticed this thread here but could not find it in the archives mentioned there: https://68kmla.org/bb/index.php?threads/interware-device-software.32951/page-2#post-398670

The SE/30 now boots nicely. Not sure if reseating the insulation foil was really the solution. It was seated before. Anyway, thanks for the guidance!

Yes, idle = nothing connected. Thanks for pointing out the missing isolation foil. Adding it didn't change the voltage on the -12 rail. Any other ideas what is going wrong? I should mention that the PSU was working fine before the recap.

After the recap of a Sony PSU for my SE/30, the Mac won't start-up (no chime, no fan). The analog board is known working. Here are the readings from the idle PSU: I wonder why the -12V is so low. Any thoughts on that? Would adjusting "VADJ" at position 251 correct that or just increase it for...

Samw issue with my GE PSU.

The link above seems to be broken.

Thank you!

Is there a 3d printing file available for the plastic lock at the bottom of the PSU's for the logic board power plug like this one?

thanks all for the insights.

Just got my first Q650. Does anyone know what the ports marked in yellow are for?

Thanks!

Can the AB be converted from an original configuration of 120V use 5o 240V use?

It did not. Certainly because of a dead battery.

After a recap of my Portable (backlit), it chimes but produces this error with and without the RAM module inserted: 00000003 0000FF00 Any thoughts what the issue could be? - Chris

Yes, it's the one from Japan. Here's a photo of the backside. No auxiliary PSU came with it, unfortunately.

I'm looking for the installation guide for this accelerator. The connection to the CPU of the Mac is my main concern.

@jessenator I just noted that the caps C21 and C25 on the small board are of different capacity in my PSU. C25 is 10uF, C21 is 22uF. Minor detail but I thought it might be of interest to others. - Chris

So, I measured the voltages as per the suggestions above. They were all within the specs. Both before the chime and after. However, I recapped the analog board. Now the Classic II boots right away. Problem solved. Thanks all for your help!
