Hi, I have the same issue with a missing C10 capacitor. Is the following Amazon link a valid replacement based on the 0.1µF (100nF) supporting 50V ? https://a.co/d/aVYrp5y

Hi, I changed the analog board with a working one and I noticed the motherboard ( 820-0250-A) is missing capacitor C10 (next to the battery and speaker connector). I found on this BOM that it's a 100nF capacitor like most of them on this board. Has anyone got a link or ref to pick the right...

I removed the floppy drive and I can run the Mac SE 30 without it since I have a BlueSCSI. This drive is the reason for the blown UJ11. At the moment the board is not starting and I will try again once the UJ11 chip is removed.

I identified the issue: the VLSI UJ11 chip (floppy disk controller) blew so I'm planning to remove it. I will try to run the board without this chip to see if it works..

Or could it be the flyback ? If so, I heard I could move the one from the SE analog board to the SE/30 (I'll take a photo of the analog board)

Is it worth to remove and test each capacitor from the powersupply, analog board and motherboard, and only change the ones that damaged ?

I followed the tutorial which went well until I connected the floppy drive to my Mac SE 30. It made a strange noise so I unplugged the drive as it wasn't properly mounted. The issue is that I smelt some burn around the Mac power supply. Testing the PSU, I get the 12V and 5V output with a...

I'll try this

Is it worth dissassembling it as on ?

If I remove the upper carrier, the floppy disk hits the head and will damageit when inserted in the drive.

Hi I removed the analog board. It's a 820-0206-B model, see photos. Some solderings at the back are dark (looks links something burnt). I'm not sure O understand the suggested solution : " Check/resolder pin 1 (bottom, vertical yoke) of the j1 connector, pin 5 of the ]4 connector, and...

Hi, I found a replacement floppy drive for my Mac SE 30. It's a Sony MP-F51W-23 (MFD-51W-03) on the side that I took from a dead Mac. Using the cable with the red stripe, the drive loads and ejects disks ok. However it identified all disks are unreadable. I noticed the upper head didn't touch...

Thumbs up as I found this thread which fixed my issue to get a floppy drive working with my Mac SE30 Using the red stripe cable fixed it !

Hi, I purchased a cheap Mac SE 5011 as I needed to replace the floppy drive in my Mac SE/30. I'm trying to figure out if this Mac SE can be restored, or which parts can be useful. The motherboard (820-0250) is in a fairly bad state since the battery leaked. I removed it and cleaned the board...

Would this cable connected to a USB to DB9 work? https://a.aliexpress.com/_EyGdV4U

Hi, I have the same issue, I want to copy images to an Apple 2GS. I'm trying to get ADTPro to work. I already tested it with an Apple 2e using a USB to DB9 serial cable. Works great. For the 2GS, I bought a USB to miniDIN 8 but nothing happened. On the video, they used the phone/modem miniDIN...

Hi, I'm restoring a Mac SE M5011 which has a Radius FPD 64KHz with a 9 pins port at the back see photos. I found this software for Mac SE: https://macintoshgarden.org/apps/radius-system-software-v25, and DB9 to VGA converters online but I wonder if this will work on a new screen or if I need to...

Hi, I came across a site mentioning Apple A/UX , a Unix based OS for Apple Macs. I'd like to test it with my BlueSCSI but cannot find a suitable image. Has anyone tried it and could send a working link ? I know Linux and I'm curious of the advantages of running it in comparison with Mac OSes...

I also had to recap my SE/30 board to get the sound working again.

Hi, A simple clean of the membrane did the job. I didn't have to use the conductive paint.
