Been messing with an AES off and on for... a while. Finally got it to boot with the Neo Diagnostic BIOS, and I'm getting this error:
My initial guess was "cool, time to swap the VRAM out", but the documentation seems to suggest it is unlikely to be the VRAM:
Anyone have any ideas on the next best steps here? I'm buzzing out the VRAM vias to the 68K, and so far so good... leaning toward socketing & replacing unless anyone has better ideas. I assume this would be the Sony CXK5814P chips.
Thanks!

RAM address errors
RAM errors which appear to be caused by bad address line traces are reported as address errors. Refer to the pinout for the type of chip used by the given RAM and ensure that the given group of 8 traces are all good. It's possible but unlikely for an address error to be a faulty RAM.
