Keeping a 35-year old system like the MacIntosh SE and its successor, the SE/30, up and running requires the occasional replacement parts. As an all-in-one system, the analog board that provides the power for not only the system but also the 9″ (23 cm) built-in CRT is a common failure location, whether it is due to damaged traces, broken parts or worse. For this purpose [Kay Koba] designed a replacement analog board, providing it with a BOM of replacement components. This also includes the neck board, which is the part that the CRT itself connects to.
As [Kay] notes in the project log, the design was inspired after building [Kai Robinson]’s Classic Reloaded logic board, which we covered previously. After a few revisions, [Kay] has now begun selling the PCBs for $42. The product page also links to BOMs for both the analog board and the neck board, with most of the parts simple through-hole parts. If the board’s fancy styling and LEDs compared to the original board isn’t your cup of tea, it does look like there exists interest in a more subdued version as well.

Need something similar for the fat mac 512k and the 1mb mac plus…
AFAIK, you can swap analog boards between 128-SE
Just from looking at the connector pinout, the main difference from the older Mac’s point of view is that the newer board doesn’t have connections for a speaker or battery. You could hack those on easily enough.
I’m a little confused as to the reason for this projects existence…those analog boards are pretty reliable and on the couple dozen or so I’ve owned I’ve never found one that didn’t either just work as is, or need something simple like resoldering cracked joints or weak caps. It’s not the early 128K thru Plus board that gets eaten alive by the clock battery. And since it’s a kit anyone making one would need soldering experience anyway, so they’d likely already be able to recap or resolder bad joints…???
That isn’t to say it’s not cool and I probably still will buy one for my clear case project, I quite like interestingly colored boards. But trying to justify it beyond that seems a bit needless to me.
I suppose if someone comes across a logic board and wants to build it out without taking parts from an existing system, this would make it possible, assuming you can source the remaining parts.
As a teenager I used to make good money tracking down broken SE/30 and working SE and swapping the analog boards.
When will the Micron Exceed video card with greyscale adapter for the internal CRT be cloned? Even cooler would be a color CRT transplant for the internal, plus an external monitor.
Bolle and friends on the 68kmla forum are doing excellent work with regards to cloning the greyscale board, and cloning a graphics board, for SE30 at least; see https://68kmla.org/bb/index.php?threads/building-an-internal-grayscale-card-for-the-se-30.39910/
As far as I’m aware, there’s no colour tube available that fits an SE/30.
When I worked in the computet industry used to repair a lot of tubeway monitors get are friends electric shock off the crt and fat electrolytics that held their charge for ages grapple monitorsxwere good not sure who made them the plastic Amstrad computers were easy to fix when the monitors got dropped itvwadxa case of we are glass we fall we break tubeway days now seem so unreal now that we have flat screen lcd monitors
Everything alright ChatGPT? You sound mixed up…
Not too many people left nowadays who know how to repair let alone design replacement boards for computers from this era. Kudos!
