Digi-Key lists Fairchild BU406FS-ND TO-220 pkg at 68 cents. Going with an original might be a safer bet. Larry Pina says avoid ECG379, it can cause left side screen foldback issu…

What a coincidence! My local goodwill happens to have a copy of Macworld Mac Secrets 5th Edition. (Don't know if the CD was with it.) Though as far as I know they're not having …

"Secrets" is by far the best Mac book out there. It covers all those things the other books don't and includes some pretty detailed historical reference sections. The software is a…

By chance a friend dropped by with a broken SE today, giving me an excuse to open one up. There is indeed a focus control. Have you tried adjusting it? If it has no effect, then fo…

Hi Gary, Did your tech check R26 to see if it is shorted or open? I ask because I've seen this exact problem on three or four Mac Pluses and Pina's recommendation to check the c…

We'll see how the CPU swap goes before I decide on overclocking. I actually have a Q605 and an LC475 as well as two 68040 donor machines, so I have some room for error. My end goal…

nb: 40MHz is not always stable though. A heatsink/fan for the 040 would be a good idea. http://homepage.mac.com/schrier/q605_40.html Output Enablers sell some useful parts. …

I'm finally getting around to swapping the 68LC040 in my Q605 for a full 68040. I have a 68040 donor machine ready to go, put I have no experience pulling chips. Any advice on wher…

Just lever the the cpu with a thin knife, SLOWLY. I would suggest no more than 1mm or 1/32" before moving on to next side and repeating, the pins are only 3mm / 1/8". Ok you cant r…

What kind of CD did you try? Are you sure it's undamaged? Is it a burned CD, or a factory-pressed one? If the former, expect trouble in older drives. Is it an HFS disc? HFS+? ISO?…

I usually use a thin screwdriver. I know, not the recommended way of doing it, but as long as you are extremely gentle, you should be fine. I've been doing this for years, and have…

Unless you have a proper IC puller, or some other device that can get under and lift both sides at the same time, then the trick is to ease each side up a very small amount at a ti…

I guess every machine is different. Since the addition of the 3rd drive, it's been noticeably warmer in my room which is nice because the heating for the house isn't so great u…

A broad (1"+) wood chisel can be used to pry the processor out of the socket, working slowly one side at a time. You don't hit it, you turn it like you might a screwdriver, and you…

Hmm... That is weird. I have my Sawtooth G4 maxed out with three HDs and it's DVD drive, Everything worked fine. I know yours is a quicksilver, but they're not that far apart. I h…

Switching both to cable select worked. Which is strange because I've always been told that optical drive buses on mac's weren't "smart" enough to know which is which and label them…

I get an address error. Can anyone help???

I install the CD Sunrise driver today with System 6.0.8 and when I stuck a CD in the drive I get a error of some sort (I can't remember right now). What else could I try? Thanks,…

JDW is quite correct -- poor focus is not caused by a logic board problem (except, perhaps, indirectly by loading the power supply; that possibility is quickly checked by simply me…

I have never had any caps "knocked off" when I have removed or inserted SE/30 logic boards. But I used to be a service tech for the now defunct MicroAge so I know how to exercise …

Dec. 31 /09 Almost New Years Eve: Thank you all good folks who replied to my problem. Phreakout (Joe), I enjoy your postscripts. Here's one I just made up: (Hey Joe, where you…

Try setting the jumpers on the back of both drives to CS (cable select). Also, take the RAM down from 1.25GB to say 512MB, if possible. Sometimes OSX will do funky things when yo…

JDW is correct on what he has said. Most display issues are centralized around analog technology, hence the analog board. If it were a problem centralized with the logic board, y…

unless that filter chip is flooding the system with noise, course if it were enough to cause focus issues on a totally different system its going to cause all sorts of havoc

You appear to be confirming what I had guessed before. Namely, that you did NOT have this screen focus problem when you first had your SE/30 operational, prior to any motherboard …
