I'm quoting JDW from an older post he had on AppleFritter: "I have also read about replacing the bourns chip (RP2), but I don't have one handy and I honestly do not see the logic …

After examining your photos, it is clear that your analog board is in good shape. But it is also clear your motherboard is in bad shape, especially in the area of C9. You not onl…

Uh oh... A database query syntax error has occurred. This may indicate a bug in the software. The last attempted database query was: (SQL query hidden) from within function…

PM sent!

TheNixer, It sounds like you have a problem with the network filter (RP2) on the SE/30 logic board. So you are correct. Referring this info to the website you linked in your las…

Here are some pictures of the boards and the ram. Let me know what you think. The last two pics look like some of the caps are bad. http://yfrog.com/izpc27011550j http://yfrog.co…

I'm wondering if I'm out of luck on this SE/30. It's a liberation that I knew didn't work but I thought I'd try my luck anyway. The great SE/30 repair reference (http://www.biwa.…

First thought: mosey over to cubeowner.com and browse the video card forum. Second, that's the way a GPU that's been running hot seems to die. Unless you had a fan on that 7500, it…

I have experienced SimasiMac on multiple SE/30 logic boards. SimasiMac in its truest form is a set of HORIZONTAL bars that are very clean with no stray pixels here and there. The…

SemperFi94, THAT is a classic symptom of what is called "Simasimac", or "Zebra-like pattern". I refer you to the following link below: http://www.biwa.ne.jp/~shamada/fullmac/rep…

Hello I have an old Mac SE/30 that, like the title says, won't boot properly. The guy I got it from said it was working fine the week before I got it but he was freeing up space on…

Well, Bunson has got me a-thinkin about a tinker with my G4 Cube again, with his reference to dual G4/500MHz cards in a Cube. I can get one of these shipped on eBay right now for a…

Yep, I got the Centronics cable, it plugged right into the back of the CD-ROM Drive. Thanks for the reminder.

make sure, that fits onto a cable to change it (which is fine if you have a 50 pin <-> 50 pin centroncis cable)

Yeah I did some research shortly after I posted the question. You are correct it's a Centronics. I found the adapter here. http://www.computercablesource.com/scsi-adapter-centroni…

I need a 50 to 25pin adapter for the cord to plug it into my Macintosh Color Classic. I ordered one and got it today but its a tiny 50pin on the adapter and not the large wide 50 p…

my problem is at C13. i am looking in that general area to see where to scrape exactly with the idea of exposing the correct copper wire. Click to expand... I don't have any SE…

Hi Jason, I responded to your email a few minutes ago. I see that JDW gave you basically the same advice I did, but in better detail. You didn't mention the reverse polarity pro…

a big thanks to JDW for such a thorough reply. just to be clear i am *not* that dexterous with a soldering tool. in fact, this whole process of cap replacement is new to me. my pr…

I have never "partially recapped" a board and then tested it. So I cannot speak from experience in that regard. But what I can say is that if you have the caps properly oriented …

i have 220uf 35v for 220uf 16v can i use this ? and the surface pads have come up off the board for one of them. how will i make a good connection now for that capacitor?

I received my replacement capacitors from Trag (thanks, Jeff) and have started to solder this morning. I have three finished, when I decided to put the board back and try it out. O…

The ones from Trag have a thin, red line on the one side. That's the positive side. Cheers, Anders

the tantalum ones are not marked positive or negative. how do i know which end is which ?
