Thanks you for help even by mail! [:D] ]'> That's a nice community. J12-12 and J12-13 +5v lines are shorted to ground: it could be everywhere along the board because C11 bypass seems fine. I'll try to remove C9 capacitor wire lead placed along the feedthru i drilled: i could have met a...

Thanks everyone for support. Wally your Se30 knowledge is amazing! I've checked all capacitors four times: their bypass grounding seems fine. Moreover i checked and rechecked those lines whose rework wasn't properly clean: J12-6 -C8+ ground line is fine J12-7 -C9+ ground line is fine...

http://img120.imageshack.us/img120/472/motherboarddrilled0mf9.jpg Into C8 and C9 area you can take a look at those epoxy glue spots that hold capacitors firmly on mobo: they are circular, clearly visible and virtually unaccessible. There are two videos on youtube inheriting macintosh II PCB...

Unfortunately something has gone wrong. It doesn't start at all, nor the monitor neither the power supply. I guess something on the main connector (12, 5 or -12) is shorted to ground leading powersupply to autoprotect. With the main connector disengaged PS starts; instead when i connect the mobo...

Thanks Wally, i've had to uncover and lift C5/C4 remaining traces (hair like diameter) and i had to solder them to capacitor. Annoying but not so difficult... I checked: -UB 10-15 and UB 11-15 grounded thru C5+, -UB 11-10 has continuity with C4+ I've some concerns if it's better to make new...

i've soldered any type of electronic smd component on newer motherboards, guitar / audio amplifier, with troubleless procedures. I've met, instead, any sort of problem with these vintage apple boards! :-) Yes, i used a 20 watt solder heating up gradually but i discovered that those apple SMD...

Greeeeeeeeeat. The best explanation i've ever read. I've drilled a little hole along the feedthru to reach those perpendicular traces connecting to ground mesh you were referring to, i've uncovered them and i soldered each arm to better secure the connection. Now multimeter says ground...

Hi everyone. I've a problem. Reccaping my SE30 i encountered a problem with C9 capacitor. Desoldering some capacitors (3) i broke their traces. But i've addressed the problem in any situation except the bastard C9. I've lost its "positive" trace and i've some concerns about its origin...

I would, i'll do but I still haven't found the best way, the correct procedure to take the traces on place. Aluminum capacitors are "infrared soldered" exactly on the bottom of their base. So if you are willing to remove there's always a risk of breaking the respective traces. I'm recapping my...

I did a total recapping because of artifacts surrounding black and darker colors: the worst was a long shadow on the right after every text string. Now it's fully functioning. http://img59.imageshack.us/my.php?image=foto21ix4.jpg http://img135.imageshack.us/my.php?image=foto3tm5.jpg...

Here in italy we use to say: Said... done! http://img98.imageshack.us/my.php?image=quadcon1cn7.jpg http://img234.imageshack.us/my.php?image=quadcon12wi3.jpg http://img80.imageshack.us/my.php?image=quadcon2fp7.jpg Rom version is 4.01. I've to sincerely say that it doesn't change anything...

Right! Thanks TylerEss. I guess the files i need are these on the bottom link http://lowendmac.com/daystar/download/software/upgrades_68040/ I'll try as soon as possible [:D] ]'>

Today i've received a daystar turbo 040 card with 16.6 oscillator (33 mhz). http://img395.imageshack.us/my.php?image=acce1yq8.jpg http://img225.imageshack.us/my.php?image=acce2ld1.jpg http://img225.imageshack.us/my.php?image=acce3qr0.jpg It works perfectly, i percieve the same difference i...

My two cents: all you need is a pc and an old mac. 1) Use Ciderpress 3.0 to convert your 2mg to sdk on your pc. http://ciderpress.sourceforge.net//index.htm 2) Use Transmac 6.0 or 7.0 on your pc to format some double density 1.44 disk in HFS format and put your sdk files into them. 3) Now...

Unfortunately a paint job thick enough to avoid rapid wearing, even if you use solvent-diluited paint mixture, will change the texture. Furthermore a paint job will generate unremovable paint collection along grooves. You have good chances to irreversibly ruin your mac at a closer look. But if...

Hi all. As said, after have it refined with 300 grit paper it has lost any sign of sanding procedure but the surface has become more... i would say "velvety", something far remembering soft-touch surface used on black macbook. However it hasn't become completely smooth nor shining because of...

Hi there... i'm writing from italy so i'm not sure to use the correct technical terms. Basically for this first step i used - 180 grit sandpaper - 300 grit sandpaper - 150 watt "square plate type" orbital sander with 4 mm poliuretane soft layer between plate and sandpaper. - 20 minutes of...

You can make an RGB to SCART ADAPTER for the IIGS http://vintageware.orcon.net.nz/apple2/scart.html Holding down "option" key during start you can choose between 50 (PAL SECAM) and 60 hz (NTSC) refresh. Hope this helps.

Last year i used an LC040 into quadra 700 motheboard succesfully. I'm pretty sure the problem you experience will disappear with a fresh install.
