I was wondering if it possible to take a screen from a Apple Macintosh Plus or SE & place it in a SE/30 ?
The tubes are identical from the original Macintosh through the Classic II. It was reported that some machines had a slightly different wiring harness so that the coil units had to be exchanged, too, but this is something I could not confirm yet. I had no troubles e.g. fixing an SE/30 with a tube from a Classic with a dead analogue board.
I found those screens (Samsung 10ATY4N) sold as an assembly for use in repairing B&W security video displays. In other words, those little screens that security guards watch for hours use the same CRTs as our compacts, in at least some cases. I bought a few of them and they came with a board similar to the analog board in the Mac Plus. The same model of flyback transformer and the BU406 transister were present.
All of this makes me wonder if Apple didn't borrow most of the analog board circuitry from a security display. Or perhaps that was just the recommended supporting circuitry in Samsung's documentation for that CRT.
