Has it had a really good clean after recapping? This is my generic checklist that I always follow if a board doesn't work after recapping. It's all pretty obvious stuff, but still good to go through. Is it clean? Check your work (correct components, polarity etc.) Check for accidental shorts...

Can I ask whether it worked before recapping? And who did the recapping?

My apologies @JDW, I had a look around but only have Rev. A boards here at the moment.

In order to get an accurate measurement of a capacitor, it can't be tested in-circuit. It needs to be removed from the board first. However, I can say with a fair degree of certainty that those axial caps are not the problem. I agree with @Elemenoh that replacing those Ux8 chips on the board is...

I'm pretty sure Formac was a European company that made display cards, so I'm wondering if this somehow expanded the display capabilities of the LC475? It's the "21" on the end of the product code that's making me think along those lines. Maybe it allowed display to a 21" monitor? Just guessing.

I was thinking that myself. Maybe even a database plug-in added to WordPress could do the trick.

For anyone looking for a DB15 to VGA adapter in Australia, you may end up with one of these, designed and sold by eBay seller "Retro ShopBox". I've attached the supplied documentation. This one does not do sync on green for the really early Macs. However, if you're like me, you can't actually...

So the little tester was actually doing its job with the failed test. Excellent!

This is the STL for the DB25 case I made. The only issue is that I made it to fit exactly with the DB25 connector I use, which is probably different to the ones being supplied by other BlueSCSI sellers. You may need to tweak things to make them fit.

I'v come up with a solution for the Mac II battery holder issue for those with a 3D printer. I've made a double holder with the correct lead spacings to line up with the axial battery pins. Just buy a regular battery holder and use the metal pieces in the 3D printed holder. Just use the metal...

Hi Craig, yes it's the same for both ports. I've only tested it on a couple of computers, but it worked for both ports on both computers.

Magnificent photos @splorp, thank you!

Have you swapped out the SCSI chip? If not, I'd be trying that next.

I suspect that the only option for the Q650 (and IIvi/IIvx) is to use one of these gender changer/extender thingies. The port is so ridiculously close to that bottom lip of the case.

There's probably a separate audio channel in there (Window > Show Movie Properties) that's being ignored by YT. Exporting it from Quicktime in another format would probably fix that.

I'll see what I can do @Kai Robinson.

Just to confirm, if you attach a SCSI device but still attempt to boot from a floppy, you get the grey screen, is that correct? So just the existence of a SCSI device on the bus stops it from booting?

I've done the same on my Mac Plus and it works a treat! I used a 1N4007 diode (because that's what I had at hand) and it works.

I don't suppose you could post some nice, clear hi res pics of both sides of the NuBus card please? I'd love to reverse engineer it.
