Two --> resistors ??? <--
I just completed a 520STfm upgrade. Used sockets, caps and of course
chips. No resistors though. Where did you put the resisors ??? I also did
the upgrade on a Rev D board.

Sounds like you ZAPed someting while you were working on the upgrade.
I would look into the MMU if I were you. You may have toasted it. Sounds like
