Before the loss of data there was a post about this. I had started making a replacement power supply for my SE/30, because I’m planning on using a FPGA to drive a LCD - no more need for the CRT, or flyback, etc.
The h-sync, v-sync and pixel data come out to the fpga as does signal from a rotary encoder in place of the brightness potentiometer. The power supply module is a Mean Well PT65B. Like the analog board before it a simple 7905 regulator makes -5v but you probably weren’t using serial comms anyway. A 3D-printed housing makes everything neat and the power inlet and switch look just like the original when the case is closed. The PSU module has the same dimensions as the old PSU so they interchange - new PSU on old analog board, old PSU on new analog-less board.
if you are doing things the messy way - mac to arduino to lcd converter board via hdmi - then this will work already.
I’m working on the fpga driving the LCD now.
