Hi!
Got a 4 Slot I am working on and I can't seem to find an IC map like you can for the AES. (Page I thought would had an IC map) https://wiki.neogeodev.org/index.php?title=MV4
TL;DR
Where is the Work Ram in the 43256 RAM assembly of the Neo Geo 4 slot?
I am getting the following errors *Attached
And I want to get in there and inspect for damage, continuity trace these RAM chips and replace if needed.
But don't know where the Work RAM resides: in the cluster haha
Also, super naive question WTH does it mean with:
WRAM Data (0000) --> is that location? like IC wise?
Address: 10080E
Actual: 0010
Expected:0000.
I know I need to learn how to use a logic probe but, curious if the address tells me which chip? Also any tips for a logic probe? I got one but need to learn/watch vids
Thanks!
