Got the PRAM holder in.

Out of (7) bad Alps switches, I could only repair (2). It looks as if someone spilled a drink in this keyboard at one point, and didn't immediately open it and clean it out. There were also broken pieces of the lower case plastic floating inside, so this may have been dropped hard at some...

That's too cool that the onboard 4Mb memory was repurposed for a RAMdisk, not much use for it otherwise. Nicely done!

The cheese wheels of impending doom, are finally gone. Big thanks to @Fred1212 for recommending the Betterbit eject gears, they are really good. Indistinguishable from the original in both fit and mesh. $5.75 for (2) with free delivery. Super fast shipping. 800K #2 operates much better...

Coming in to someone's thread, just to say they're doing it wrong, isn't going to go easy. Maybe change the tone of the entrance, to include your specific experience of a time when you saw someone actually bridge their floppy drive sitting it on a flat surface. I am enjoying this Mac SE so far...

After all the work I've done here, do you really think I'd risk bridging the circuit board of the floppy? The floppy chassis can sit on a flat surface without touching anything, there's clearance. You are welcome to do what you think is best, for you, but don't expect everyone else to agree.

Received the eject gears from Betterbit today. Went from Cheddar to Swiss. Used the same lube as the JDW 800K floppy rebuild video, followed that video carefully throughout. I only used (3) of those soft vinyl washers, the assembly is solid and stable, seemingly without the fourth...

I appreciate the reply, thanks! I was so new to the Alps switch overall, none of it made much sense. I've finally got a a grip on it now, thanks to the second YT vid above. I always really appreciate when someone takes their time to make in depth videos like that, commendable.

Was able to get the switches open, I took two apart, and they were very clean inside, not what I expected to see. The contacts are shiny and new in there. This video explains how to bend the contacts inside to get them to touch again, which is what's wrong my (7) switches.

This makes more sense.

These switches are caked with, who knows what, it's not easy to see the tabs press inward. Thanks for that!

De-soldered the bad Alps switches. This one had the circular trace flake off: Looks like water damage on this broken switches legs, some kind of rust. Are these the ones sometimes called salmon switches? A continuity check proves these are not conducting when pressed. Is there a safe...

Can you provide the pics of your Analog board?

I have a working BlueSCSI v2 desktop board here, but I don't use the berg floppy power connector. The only jumpers that I have closed/enabled, are the Termination Power On (green jumper), then PWR_ON, Back Feed jumper is off, 3-pin Initiator set to Target, other Initiator 2-pin header is not...

One more peroxide treatment on the space bar, and it should be done.

Cleaned off the PCB, there are no broken traces, was not in the right spot earlier. Plugged the Extended KB in on the left side port, and nearly all of my keys are working now, including both Shift buttons. The green tombstones are the ones that are extremely flaky, or completely dead, those...

7.0.1 seemed fairly quick with BlueSCSI, I'll make both the 6.0.8, and 7.0.1 images. Want to try 7.5.5 again without all the add ons from Savage Taylor, wondering if that's where the Apple Photo Access module that never works, came from.

Got the KB broken down. Will peroxide the space bar today. A couple of suspicious spots, and oxidation on the bottom of the PCB. Tested this area with a DMM for continuity, the traces look bad, but they are connected still. Will most likely run a jumper wire over the worst looking spots...

Got the same two errors with the corrected hardware spec image, tried unplugging the KB too, to see if that had something to do with this, same issue no matter what. Going to give up on 7.5.5, and focus on 7.0.1.

Are you saying I should make the Baillisk II, 7.5.5 image, use all of the same specs that are in my physical SE? I was under the impression you could use any spec for the Video, CPU, and RAM in Basillisk II, and yet the physical SE would figure out the actual possible specs on its own. I'll...
