It has been a while since I worked on my Colour SE/30, but inspired again by the most excellent Mac84 working on his, I recently made some further progress with mine. I tracked down a molex to DC power cable, which allows the LCD panel to run off the single power supply running the main logic-board, rather than a separate mains transformer. I also borrowed the metal internal frame from another SE/30, as well as some of the screws. Will have to figure out if that is temporary, or if I will need to source extra so the other one doesn’t have to do without.

This weekend I 3D-printed a display bracket which allows the flat 8.4-inch LCD panel to sit flush in the space previously occupied by the curved CRT, here is the version I went for. The next things I need to do are to re-cap the main logic-board, as the capacitors are showing signs of leakage, as well as figuring out a solution in terms of internally mounting the power supply and solidly attaching a short power extension cable and a power switch to the exterior of the case.

Mac84’s one has an Ethernet card which was designed primarily for the Macintosh IIsi, which uses the same PDS (processor direct slot) as the Macintosh SE/30, the difference being that it has a NUBUS card slot coming off at a right-angle, which then has the NUBUS card sitting parallel to the main logic-board. When installed in a Mac SE/30, that would have that NUBUS card occupying the space where the floppy drive and/or the hard drive sit, his solution was to de-solder that NUBUS slot, and replace it with a connector that is itself right-angled (I think this one?), such that the NUBUS card is sitting perpendicular to the logic-board.

It’s a neat solution, I may see if one of the Macintosh SE/30 models I have with an Ethernet card does have one of those models with the NUBUS slot, it is possible… If not, I may stick with just copying across data a different way, although it would be nice having networking ability!
