The strange thing is that your SE was working before the new caps… and the SE is not known for having capacitors issues, had a few and most worked with original caps. A broken pad somewhere ??

when the disk is in, the top carrier must drop and a switch will spin the disk. So, this can be faulty or the carrier can be twisted.

Concerning the SE/30, probably UE8 (LS166) faulty. The SE… can’t help, can you post pictures ?

Yes the ground clip should be there, but most of the times is lost. As soon as the logic board is removed, the clip tends to follow the motion, and forgotten in the process.

The fail message error is related to the lock switch probably stuck, broken or faulty in your floppy drive, not an issue elsewhere. Or… the lock is on…in all the floppy disks you are using (bottom left)

Known issue with PDS connector going bad with cap goo, i will clean the board with IPA first then test traces with a multimeter.

You probably have a broken trace somewhere (or more) If you have another SE or SE30, you can try swapping things around to be sure. Not an easy fix

Not much more difficult, the 400k is seized solid most of the time.

As always, the first of a kind is more sought after than following models. For instance, a Lisa 1 (if you find one) is far more expensive than the Lisa 2 that followed (even a Lisa 1 modified by Apple to the newer model) For the Macintosh line, the 128k was the first, and if you have the...

I agree a 100%, a complete unit including the original carriage bag but modified to a Plus LB was sold recently for 600 dollars, wihile another 100% original identical unit was sold for 1500 $

Hi, as always, prices are related to what people is willing to spend for it, but also what a similar item has been sold recently. Macintoshes 128 are sought after, but a complete unit with all paperwork and accessories will worth more than a single unit not working or not complete. The floppy...

i was thinking using two binaries in a 27C512 eprom and swapping from one or another for a Standard Rom or the newer 4X. Anyone has done that already ? I think using a switch on pin 27 (A 14) to get it working (probably even using the standard logic board bridges to do so)

I think bad as well, maybe the Roms and SWIM can be saved.

Yes, ok, yes this is basically more or less the same unit, with a different board and a different enclosure and size.

For those Roms in the LC, they are pretty common indeed, the very first batch was sold with those "Confidential" tags on it, should have two LCs with them, just an early model, nothing more.

IIRC there is a fan inside the PSU (but can be wrong) anyway most Apple IIs and early Macintosh don’t have a fan.

If capacitors are the original ones, you can start replacing all of them.

Concerning the SEs, the SE (without any other label) should be the 800k drive, the other two ones have the 1.44 Mb drive, and were sold under the FDHD (Floppy Drive High Density) or Superdrive name, but they are the same. Ths small monitors can be used for Apple IIs A lot of work here, i will...

Agree a 100%, the drive itself will work fine with the Macintosh, but reading old data from it won’t be straightforward.

I agree, had two bombed SEs and both were repaired with little work.
