This is great, not just the characteristic Jobs response but the thought of a professional designer seeing something that's already sound from an engineering/physics perspective and not wanting to upset the balance. I'm hoping at least one person out there has an account of the time Steve...

Well said about the actual rotation distance, that's an important clarification I never mention. You'd want to fatigue the legs and nothing else. They usually break farther up, with the force concentrating at a thin/weak area that's not right on the pad.

So in theory, all we'd have to do for it to be considered sane in general is to twist SMT electrolytics off of all kinds of PCBs?

I took a second look at my IIci, as I've never had to touch the RTC in it yet. It's not only a different pinout from the previous-gen 8-pin one, but a different package entirely. I might have to probe mine now for better reference, since I was looking at a IIcx where the clock circuit had...

AFAIK, whichever crystal is the 32,768hz one, in proximity of the RTC, is its clock source. If it's anything like the SE/30 and IIcx (I think the logic is almost identical but the pinout differs?) then the 1hz source, an interrupt, starts from a leg of that 8-pin RTC. It is completely possible...

Have lifted no pads with the pure axial/twist method, even on the worst boards I've had. Gentle heating and attempting to walk off a capacitor has managed to do it, though. With a more precise preheater and hot air nozzle it should still be possible, but the flush cutters still sound the most...

You just have to adapt a 6800 to the 68000's bus to make it true. Or find the Jef Raskin era, 6809-based proto-Mac that lives in an Apple II.

I assume by "mostly vertical bars," you mean the default NEC VRAM state? Have you tried any other cards in that same SE/30 before? I've had expansion cards other than the Asante MacCon (which I assume is because it doesn't use all the PDS lines?) quit working when the power supply and the card...

The neckboard, or the yoke? I assumed the socket/pinout on the neckboard would require that to rotate with the rest of the tube. From what I understand, yoke angle can rotate the image and neckboard is primarily for supplying grid/heater power and ground. I'm still trying to reason why this...

This is pretty weird, but I swear qemu-system-m68k emulating a Quadra 800 produces these exact same artifacts, when I use it (Mac OS 8.1). I am certain the rectangular outline one has shown up several times, like the damage/repaint isn't working as intended.

Really? I wonder if that's a normal amount for the cutoff pot, then, and whether everything was manually adjusted by technicians at the plant. I'm almost certain I remember just a tiny, almost-invisible amount of rotation/offset being within spec for Macintosh CRTs, too. The actual geometry and...

Finally, I can not only plug in Ethernet cables, but also get them back without surgical tools!
