I had some time for this recently, so I started by checking if the CRT and analog board are OK (by using the Pi to generate the hsync/vsync signals). Right away things are not looking good: the CRT lights up for a fraction of a second and then goes dark. During that short time I can see a white...

The logic board outputs 5V TTL. The analog board turns that into a 1V signal. The CRT boards (both Apple's and Micron's) amplify it to 30V. The Micron expansion board also outputs a 1V signal, but greyscale. I know. But if the video signal output by the analog board is higher than the one...

I figured this part out; it should be OK. Signal voltages are also the same. From the patent:

I don't intend to use it as a Linux machine; I have enough of those. My plan is to install a classic Mac emulator such as Basilisk II and make it run full-screen; this will let me run period-correct applications. The resolution shouldn't be too much of a problem in that case. I know all of this...

[First post. First classic Mac. Amazed of the following these things still have.] I was recently given a Mac SE/30 with its keyboard and mouse. Looks relatively clean on the outside; inside, a different story altogether. Battery has leaked and completely destroyed the logic board; I mean...
