DRAM 128K system has stopped working

[CheshireNoir]

Hmmm. Always check your work.
Went back and checked my rework on the main board, and fixed up two problems that I'd missed on my re-rework pass. Multimeter in resistance mode for the win! (A link I thought was cut through wasn't and a jumper turned out to not be as conductive as I thought)
Can I just clarify something in the Hardware Notebook?
Section B Pg 13 under DRAM MAIN BOARD is the following line:
   LINK SET 4.    cut K. to L. join K. to J. (only change if DRAM core board IC48 is used).
I interpreted that as "Don't make any changes if you don't have IC48" but it could mean "only cut K. to L. if IC48 is not present"

BTW, fixing those patches and verifying them, things seem to have gone backwards. The RAM tests no longer work.

I'll do some more tests.
Cheers!
