My SE Restoration(Pic Heavy)

[eweri]

Wow - looks really good

Looks like the termination resistors of the drive have been bent, right?

I wonder if it starts up when you put all things together.

Could you elaborate on what you mean by the "termination resistors being bent"?

The black things, near the interface, in the last pic, were originally standing up straight, but were bent so they are now laying down completely flat. In general, you don't want to do that to those resistors since that can snap their legs, or if you try to stand them up again, they can also snap.

Thanks, I'll be more careful of those

Finished cleaning the power supply and its reassembled and ready to go. Also put the hard drive back together, though I'm still skeptical that its going to work. Took the floppy mostly apart to clean but stopped after I stripped a heavily corroded screw. Not sure about the fate of the floppy since the internals are all in pretty poor shape. But for now I should be able to attempt a boot without it. Cleaned the analog board today and its in the drying process. Once its dried out I plan to reassemble for the first test. And finally, I spent the last 3 hours scrubbing away at the case with a scotch brite pad and I am actually rather surprised at how well it worked. A pretty poor case now looks fairly good.

 

[uniserver]

wow it looks like new

it would be cool if it fires up and at least gives you a :?: screen.

Spent some time this morning and its all back together minus the floppy drive. Plugged it in, and prepared to flip the switch not knowing if it will magically boot up or possibly short and catch on fire. So I flip the power switch and... absolutely nothing. No sounds, no movement, no sign of life what so ever. Got out my multimeter and the power supply is not giving any output. Next step will be to disassemble the PSU again and start testing connections, though I suspect in may just be the contacts in the switch itself.

 

[uniserver]

sounds like dead caps in the power supply.

 

[bigmessowires]

Rats. It looks great all cleaned up! I'm looking forward to seeing your eventual boot-up photos.

 

[harryk]

sounds like dead caps in the power supply.

Do you know how I can test them?

 

[uniserver]

yeah if you look closely you will see the smoothing caps are leaking

Listen very closely, listen for a slight click click click, also there is a fuse in there you can check.

 

[macclassic]

Wow

 

[macclassic]

I'm hoping it will work too, fantastic work so far.

 

[Ike]

I'm surprised how little the case is yellowed, while the apple badge has quite severe discoloration.

It cleaned up amazingly well, I hope you will get it working without too much hassle :O

Keep us updated!

 

[harryk]

So despite my best attempts, I cannot find any obvious faults with the PSU. I can't see any visual signs of leakage though I probably washed those away. Now the plan is to replace it, so if you've got one that works and want to sell it let me know.

 

[beachycove]

a) have you tried looking at the fuse?

B) your location?

Fuse is fine, unless there is more than one to check. I'm in Denver.

one of the se's i jsut got, had a miniscribe HD, it wouldnt spin up so i had to open the cover and rotate the spindle back and forth it was a little gooy,

This is my first post. All I can say is I'm amazed. You guys here really know your stuff. I have electronics training from the Air Force but not like the stuff you guys do.

I bought a Mac SE,1 MB RAM, 2x 800K way back when they were new. Sold it a long time ago and now getting back into it.

I have a lot of questions of you don't mind.

Within the last three weeks I bought from Craig's List and Ebay two Mac SE's.

Both have 4GB or RAM so they were upgraded from 1MB.

Both have single 800K floppies.

One has an internal Apple 50 MB HD refurbished by a guy in New Jersey named Herb Johnson, anyone know him? Found him on the web. Anyone know anyone else who does work on SE's?

I have coming from him a 1.44 floppy and a friend is selling me his board with the three 1.44 SuperDrive chips that I will remove and replace on my board, I'd use his but his battery is dead.

The other SE has an internal HD @ 30 MB.

Screens look good but both are very slightly tilted to the left but I don't want to mess with the yoke.

One also came with an 80MB external non-Apple HD which works great.

Been spending a lot of time de-yellowing an ImageWriter II, two keyboards, and mice, have pics if anyone's interested. Found many different processes but this one guy's is easiest and very fast.

Questions:

1. Both these boards have soldered batteries but one looks like it may have been replaced because on the back side the soldered joints look newer. One is 1987 and the other 1988. Will I need to replace them? They still keep time. It doesn't look too difficult, just desolder and reinstall right? Where would I get batteries?

2. I see a lot about caps, I guess they're on the other board right? The one next to the tube? Will I need to replace them?

3. On both tubes I saw what looked like black grease which cleaned up, have pics of that too. What is that stuff and how did it get there? Was right on the rubber anode cover and on the glass.

4. Any recommendations?

All I want to use one for is Comic Strip Factory, Word 5.1a, and HyperCard 1.1 as I'm running 6.0.8 and have no desire to go to SSW 7.xx.

Thanks.
