I filed my cheap amazon keys down a bit and now they fit quite well. Next step, cut them down and 3d print a shell. -Dan

I'd bet it can be filed down. The ones I bought are also the quality I expected of a cheap Amazon product. I wouldn't be surprised if they are slightly out of spec.

That actually worked. I bought a pack of A126 keys from Amazon and was able to reposition all gates to fit. Interesting thing, it also works with my 089 key too. Only thing is, the a126 key is a little tight in the keyway. Beyond that, it works quite well.

Good to know the terms too. Gates. Makes sense.

Very cool. I saw that snap in the back on mine, but didn't try to pry it open. The locks use a standard keyway, so you could probably buy an off the shelf one and 3d print the key back. I might just try that. I have an extra quadra lock with no key.

I recently got a nice looking vintage Apple 16" Color Monitor that had been in a hot garage for the past few decades. It had obviously been used quite a bit, but the tube has no burn and the case is in nice shape. After cleaning it and giving it a cursory inspection, I powered it up and...

Yes I have. I've been chasing down broken traces for a while. Mine has the same double bus fault. I've followed all the data and address lines, and they are good as are all the clocks and rails. I even replaced the obvious GAL, no luck. Next step is looking at all the vcc's on the CPU and...

How do you get them apart? The AWS locks are all metal and there's no obvious way. On the manufacturer web site, they say they can't be rekeyed.

I'm out of them, but have some ongoing searches in the usual places. If I find any more, I'll make sure to tell you.

So, the long and short is this. The lock is assembled at the factory and cannot be re-keyed without destroying it. Post a picture of the key you have. I *might* be able to get another 900 series lock without a key and I know what the one it uses looks like. Also, post the key number...

If it's for the hard drive and you are using a 3.5" drive, then the same one that the SE and SE/30 uses will work. I am actually shy one for the floppy drive, but that's also the one that will work in those machines too.

A little late, but better than never. I just bought a Quadra 950 that came with a Precision Color 8-24X and it had ROM v 1.3.1. See attached, it's still a 27c256.

Ouch! I can see why. At least it's easy to fix. Attached images are some of the trace repairs I had to do on my system. After this, I scraped more rot from other traces and tinned them to protect what copper remained. I'll eventually clean it up the rest of the way and hit it with a...

UB2 on mine had the same damage as yours, though yours was a little further on. Mine also had the typical damage to traces near the battery. I wound up doing a fair bit of microsurgery to fix those and also had to scrape a lot of resist on neighboring traces to remove corrosion, then I tinned...

There are a few common failure modes to aluminum electrolytic capacitors. Heat buildup, over current, age breaking down seals, and poor quality are some of the modes most of us have experienced. That said, there is one failure mode that's not so obvious, and keeping a capacitor in a cool dry...
