Can't wait for the Gerber files to be released. I have a Macintosh Classic who's board has some issues, and I'm sure I didn't help it at all. And a 2nd board where the battery has eaten most of the corner up and ruined at least 5 traces. Tempted to order a board from MacEffects, but there's...

That's how I'll do it if I can't fix what I got and start with a new PCB. I'm not with the board at the moment, but I think I recall a large solder bubble on the bottom side of the board, may be from where all the solder seeped down from under the SWIM chip. When I get home I'm going to try to...

The issue is (as far as I can guess) on the logic board, on the SWIM Chip connector, there's 3 sides of the chip where pin 5 and 6 (I think thats where it is, I'm going from memory as I write this) are joined from what my multimeter tells me. I can't see a sort visually on the chip or board, but...

That’s with no drives connected. Just the logic board and the power connector

I made the swap and it’s much worse now. Nothing happens on boot. Fan doesn’t spin and I get a rapid high pitched beeping. I’m gonna put the original swim back and hope for the best. If I botched it, is there anyone here who repairs logic boards?

before I make the swap from the two classic motherboards, just want to make sure these two chips are interchangeable. Most of the numbers match. So I’m assuming that’s good. But the first two sets of numbers do not. Thanks everyone!

Thanks for the reply. Is there a place that sells replacement SWIM chips? I could take one of the board I was going to attempt to repair, but if I can just order the chip I'll do that instead of making the spare, possibly repairable, logic board a donor board . I'll swap the SWIM and see if...

I tried using the Drive image of 7.5.5 from this site on the BlueSCSI (incase it was a driver issue, I'm not too confident in the 7 installer disk images I found online) so figured I'd try a pre-built image. Assuming it's fully there with drivers, I booted it on my Classic and same issue. :( If...

Hey Everyone. I recently got a Macintosh Classic (I'll post photos soon) that I took apart, and restored (cleaned up, new caps, repaired drive (for now, soon will be a Blue SCSI once the parts arrive from Mouser) cleaned and re-lubed floppy drive, etc. Has the 4MB of RAM upgrade, original...
