Double check the repairs on back of the AB near RF16, and TP39. From the pic, it looks like there are bridged traces.

Yes, the PLCC's while in their sockets, sorry. Good Luck!!

Check the components inside the PLCC's for continuity. I am getting better results eliminating the PLCC sockets and soldering the components directly to the pads.

DING! DING! DING! Yes, it's from an SE. You Mac gurus sure know your stuff.

here is some fun trivia..... I found this rubber gasket inside a compact Mac and had to share because I have never seen one before. Does anyone know what it is?

Here is my Umax primary 604e 225MHz. These cards need to team up in a in a Supermac S900, if possible....... Would definitely make a great video!

To make sure you get a 'Mac compatible card that would run under OS9' source one that has either the Mac compatible DB15 (2 row connector) or the word Mac on the card/label with a DE15 (3 row) connector. Most Mac PCI video cards I have seen will have both DB15 (2 row connector) and the DE15 (3...

Hi Ron, Not sure I can recommend a NIC, but I have a 6360 with OS 8 that has a Farallon PCI NIC. It is a PN996 10/100. Hope this helps.

Thanks Kai. Hate to wait for shipping from China, but I may have to pull the trigger on those. I do like that they're listed as 'new'. Thanks again!

Working on Mac Classic analog boards and wondering if anyone can recommend a good source/supplier on the Power Supply Controller TDA4605?

Glad to hear you got your Color Classic running again!! Thanks for sharing your experience.

Ok hopefully that'll do it. Letting it air dry is ok too, but I prefer shooting compressed air on the wet board and components to blow the alcohol all around, especially in those hard to reach places.

Hey Luke- I just saw your post and wondered if you gave it a good alcohol scrub. If not, try spraying it down with 91% isopropyl (or higher), scrub the board and components gently with a toothbrush then blow it dry, preferably with an air compressor. Hope this helps. Good luck!

I think this is the logic board you're referring to with yellow silkscreen, notice it has the common green traces.

Has anyone ever seen yellow traces on a Macintosh SE logic board?

You are correct, you will need the 1000µF 35V capacitor for CP2. There are two variations of the Classic analog boards. The earlier 630-0395 (yours) has the large female CRT power connector. The later Classic and Classic II's (630-0525) have the 4 naked power pins without the plastic connector...
