By the way, I found this interesting:
After a bit more research, it turns out that it is NOT a chip but a Micron CRT video board, as shown below in the first picture. In the second picture is a homemade video board.
Now, that is Tinker differently! We need to identify specifically what that homemade CRT video board is and see a modern solution that could replace the existing CRT video board attached to the CRT. Imagine all compact Macs being able to display in grays if this were to be pulled off? The current barrier would be a video adapter device (PDS for SE or SE/30 and external SCSI for older compact Macs) is still required.
"SE/30s have been hacked to an even greater extent. There are many different things people have done, but one popular (if rare, and dangerous!) upgrade is to find a Micron XCeed graphics chip. This chip fits into the neck of the CRT, which is a dangerous place to work because of all the built up charge. When installed, it will allow the monochrome 512x384 display to use 256 grays at 640x480!"
Of course, the grayscale graphics chip, probably from the Micron Xceed grayscale adapter, would work on the CRT. I wonder while that grayscale video displays on the CRT, a separate 030 PDS video card would drive an external monitor in color.After a bit more research, it turns out that it is NOT a chip but a Micron CRT video board, as shown below in the first picture.
