I didn’t trace out the schematic but I satisfied my curiosity in other respects regarding the insides.
It comes apart easily with two small philips screws on each side, but the harness for the display is short and the harness needs to be disconnected from the board to remove the lid. Sorry I didn’t realize that this picture was blurry; I’m not planning to pull it apart again to get a better shot:
After removing the connector blocks, disconnecting the fan, and removing five more philips screws from the board, the board lifts out with only some gentle work moving the anode and cathode lines around.
Here’s a few shots of the circuit board (sadly, the picture I thought I took of the whole top of the board I apparently failed to actually take, so that’s missing here):
The RJ-45 jack is clearly there for remote display. It shares its net with the display header.
On the bottom (sorry for the glare) you might be able to see at the lower right that the six-pin horizontal header near right on the bottom of the picture has traces going to the staggered set of eight pins on the RJ-45 jack at lower part of the right side of the board:
Then there’s the back side of the display:
It has an annoyingly unlabeled chip:
In the Monocle, it happens to fit nearly perfectly with M4 screws and DITNs on the rail under the laser tube:
I had not been sure how I was going to mount it, but now I know!
