See why you should NEVER use logic?

Uh, well, if you insist...

Cut ONLY the resistor marked 256K. DO NOT cut any other.

(However, if you DID cut too many, send me the useless $3000 paperweight -
I would LOVE to solder back a resistor and get a free SE... ;-} )

This is true whether you replace only two banks or all four. If you replace
only two banks, put the 1Meg parts into the back two SIMM slots. Simple as that.

Hint: Cut only one end of the resistor and angle the body about 45 degrees.
This way, if you ever change your mind, it takes only seconds to solder the
resistor back.
