23-037E3, you mean. The top of the 0 is scraped off.

Is that rom dumped from a 100A or 100B?

Does the rom have any different marking on 100A vs 100B?

There is also an undumped soldered down 82s135 prom, 23-090B1 near the left edge of that image, around the centerline.
At some point we should dump it, but probably not immediately necessary unless it holds something really important. Do we have schematics of this board?
