Fantastic work! The Cubes and stations are identical in operation, so this should 'just work' with a turbo cube. I think it's also very likely this will work without modification in a nonTurbo model (25mhz bus). I would love to give one of these boards a spin and can test across models. The NeXT...

Also can confirm, the 110v supply is 100% compatible and will generate less heat in my experience which can only be a good thing. 

Yes, male solder cup connectors only. I was quoted a minimum of $25K to do the female board mount version... 

Is there any existing board layout for a 30pin simm? I'm not sure if it's just me, but I've started encountering a larger number of failing simms these days. I'm also noticing the prices starting to creep up on ebay for larger modules. It's to the point where I think it's worthwhile to try to...

It’s working well for me with the exception of my mouse. The new version was supposed to have fixed it, but I still have issues where I have to unplug/replug it. Other than that once you install an ssd the mini is the perfect os 9 machine and is small enough to live on my desk full time. 

Have you tried some contact cleaner on the crt pins? 

I would say leave it intact and don’t do anything you can’t reverse on this one. In person I don’t think its quite as distracting as it shows in images. Really glad you’re happy with everything! 

Yeah, it was really common to reuse the os disk because blanks were so expensive. Unfortunately the canon MO mechanism is custom to these and their own branded version of the drive.  Further the next optical encoding was done in hardware on a custom ASIC so even the canon drives sharing the...

That was an amazing deal! What MO disks came with it?

You'll want to recap that "new" logic board as well...

You can access over serial but the problem on the NeXT is that this option is not configured by default. You need to be able to boot into the machine to enable it which limits the usefulness... 

Looking forward to this!

Interesting! Just bought a set to try. 

I think I got my stash from a s-100 RAM board. If you are patient you can probably find one cheap. 

That's what makes it fun. 

I have a few SE boards and wouldn't mind assembling one of these repros for testing. Sounds like fun. If there's a spare let me know. Definitely +1 for the SE/30 board!

It would be very cool to have a replacement board for battery bombed systems. I just decided to give up on one today after days of debug. In all cases I've seen the custom ASICs look to be salvageable.  Populating a replacement board would be much faster than going down the rabbit hole of trace...

Excellent work! My favorite machines in my collection are the ones that originally looked the worst. Is there a hardware diagnostic utility for the SE/30? On the NeXT side of things we have the factory utility for some of the machines which I run after something this extreme. It seems like there...

Anyone have the schematics for the g4 Mini?

Luckily the power key is isolated from the rest of the keyboard circuit wise. I would suspect the mechanism itself is dirty. You can try putting some contact cleaner on it to see if that helps. You need to check continuity across the bottom of the board to trace the problem. It's been a while...
