Any chance you could make a schematic of the DX dram board?

I'll see what I can do. 👍

Sorry, haven't had the time to really undertake a task like that... But while I finally had it apart to replace the CIC with an OEM one--which did end up fixing the problem of it not booting without a cartridge!--I took some close-up pics of the DRAM board, and even lifted the plastic bit on the header so you can see where all the traces go.

It's the best I could do at the moment. At some point I would like to make a full schematic though.
