It’s the same thing you have to do to use a PiTFT display. The emulator I was going to run needed to have a bit of code changed. It assumes a 640×480 display, and this setup uses the native Mac resolution of (something like) 512×348. That’s all I can remember off the top of my head. If you have any problems, contact me and I’ll dig in and see if I remember what I did! I still have the original setup, so I should be able to test things.

It works because you have the juice flowing into the CRT maxed out (full brightness) and when you yank the power cord the CRT desperately is searching for more juice to keep itself alive. Because of that, it grabs all the available juice it can find in the electronics powering the CRT until they run completely dry. They run dry very quickly because the CRT is maxed out in brightness. If you are dissatisfied with that layman’s terms explanation, think of it in terms of a load on a capacitor. There are certain types of capacitors called “memory capacitors” that keep clocks or memory alive (for several days or weeks, until the capacitor runs out of juice) when the main power is cut. These caps can keep the circuit alive for a long time because the circuit attached to those caps sips very little power in the first place.

Now compare that example with the capacitors in the power supply of a Mac Pro computer. How long do you think those caps can keep the computer running after you yank the power cord on it (however big, fat and physically large they may appear to be to your eyes)? Milliseconds at best.
