WRONG.  The SE/30 uses the same memory configurations as the Mac II and IIx.
There are NO jumpers or resistors to cut.  The confusion is due to the fact
that we revised the SE motherboard from resistors to a jumper.  See Technical
Note #176 (February 1989) for an update which covers all standard memory
configurations for the Macintosh family.
PS - The 5 MB configuration is legit ... just like with a Mac II.
