I got myself a nice B&W G3 tower. I'll upgrade it with parts I have on hand. I have a NEC made internal ZIP drive I put inside the G3. But the drive sticks out around 5 mm. I dont think thats gonna work with the drive bezel I have to aquire. The screw holes do align and there is no other method...

I think I'm okay with this screen. Maybe there are some geometry issues, but I dont feel confident fiddeling with the magnets to work out the issues.

Thats Snooper 2, a Mac test suite.

I cant believe it. Probably the fault was a dodgy solder joint. I reflowed around the transformer area and this did the trick. But there is work to do and this is what I'm afraid to do. The picture is shifted towards the right side and towards the bottom. I think I saw some videos on adjusting...

Its working. Dont know what exactly I did but now it chimes and after a little while I see a floppy icon. Whoooo.

Parts arrived today. I replaced CR21 and also the bipolar cap which I did not had at hand first time. After reinstalling the AB I now get a checkerboard pattern. Progress :) Maybe it did this all the time but reflowing the AB a second time helped get it working. Unfortunately replacing the two...

I'm waiting for parts to arrive. As soon they are here I'll report back.

The cable harness is fine. It has continuity on all pins. My one has no inbuild fuse as some seems to have. I checked a few components which were related to the 12V generation. CR21 has continuity in both directions. Thats wrong. Also i measure a resistance of about 44 Ohm, also in both...

Yes I reflowed nearly all connections on the analog board. I did not check the cable. Will do it. The connector on the logic board side is okay. No cracked joints.

Regarding recap I have to add that I did not replace the one bipolar cap at C1 cause I did not have such a cap "on stock".

Hello there, I got a Mac Plus of unknown condition recently and I'm attempting to revive it. The logic board does look good after a little deep clean. The analog board is what makes me trouble. I recapped it with Panasonic caps, replaced the Rifa and tried to start it. The moment I turn on the...

I want to bring this thread to an end. I replaced the Q4 diode and the drive works like a charm.

I'm not sure if the problem is the logic board. I disassembled the remaining bits further. On the back side of the analog board I spotted some suspicious areas. Right under the flyback and under the large transformer it looks like cap leakage. Maybe this is only flux, but why is this not on the...

I now freed the analog board in the hopes to spot an bulging or leaking cap. But nothing. All looks exceptional clean. The machine must have been died right after warranty expired. Also the CRT and the anode cap are nearly free of the usual black sud. Are there any caps to look after? There...

I got two early 2000 iMac G3. Both of them are in different need of repair. One powers up perfectly but has a cracked case and a scratched screen. The other one looks way better but does not power on. I could make one good machine out of the two but rather would try to repair the non-working...

I'm not that deep into electronics, at least at that level. Could you explain why Q4 blew up when the eject motor was not attached? It blew within a fraction of a second right after turning on the Mac. I could not even try to use the drive at all. Why did Sony design it that way. Its not very...

My drive did blew up components when "used" without the drive eject motor attached. 🧐 But this could be pure coincidence.

It should be a "2SB624" which goes on Q4. I ordered a bunch of these on AliEx and hope to get this drive working again. While Q4 blew up I tested the drive without the eject motor in place. Could this be the root issue of blewing up Q4?

Rest assured I wont throw away the drive at any time soon. :) With the help of a picture search I could validate that the blown component is/was a transistor with a "BV5" marking. I'm currently checking suppliers for a suitable replacement component.

I was renovating one of my Compact Macs floppy disk drive. Its gear broke in pieces. I took the chance to clean and grease it. Upon reconnect it i heard a short electrical crackling. I imeadiately shut down the machine. Upon inspecting i found an broken/chipped component on the disk drives PCB...
