Is it worth all the trouble when you can just sit it on an external SCSI drive?

Cool. I should try that with my LCIII. Although, it's tucked away right now. About a year ago it was giving me problems about powering on. Half the time it was hit or miss so I ended up cannibalized it for the hdd and floppy drive. I've been thinking about pulling it out of the closet and having...

With capacitors, it's true you can't measure capacitance in circuit. You can, however, find clues as to whether or not it's good with resistance and voltage measurements. You should see resistance across the leads if it's good, 0 resistance if it's a short. As far as voltage, you should see...

Pics, pics, pics! I love the portrait displays. I've always wanted one.

Cool, if that is indeed a SCSI to IDE converter in there you should look to see if you can draw up a schematic so we can make more of them. Being so old, it probably doesn't have any surface mount parts and would be an easy DIY project.

I just scored a 575 on eBay in working order for $60 bucks. Can't wait to get it in.

My LC575 has shipped. I'm going to swap the guts when it arrives. Hopefully with that working machine, I can pin point if it's the other analog board or logicboard that's bad.

Speechless.

Yes, read two posts up for results.

I adjusted the pot until I got 12V and 5V and boom! It booted right up. It did seem to take forever to boot off the System 7.5.3 floppy that I forgot was in the drive, but at least it works. Even the keyboard and mouse worked once it got to the Finder. I restarted it again and the screen went...

I guess I'll be on the lookout for a new analog board. I posted a WTB in the Trading Post.

No. No spares.

Yes, still does it.

Wow, you think it's the analog board too? I even pulled the analog board out and looked at it. There's no signs of any leaky caps.

I'm reading voltage accross all the caps, so they're making contact with the board. However, I took a voltage measurement at the floppy connector and I'm only gettign 4.79V and 11.57V. Also, if I power it up without the RAM board in, I get the slightest hint of a normal screen at the top...

I thought of that. I pulled the 2 extra RAM sticks I have on the RAM board. Instead of getting the double high checkerboard you see up top, I get this one: Unless it's the onboard RAM that's bad.

Got my caps in. I just finished recapping the whole board. I did a god job of cleaning all the gunk off the board too. Sadly, I still get a checkerboard: Any ideas?

Here's the tiger one. (png for reference.) The MacPaint file is in the attached zip. I can't find the Landscape one. Tiger macpaint file.zip

I think you're talking about this one.... I'll have to see if I can find it. I don't think I have that one. I may have to find a jpg or png that someone posted and convert it.

This one? I have it on a disk somewhere. I'll have to look for it. I think it came on a HyperCard disk. (But don't quote me on that.)
