According to the manual that I got with some chips from Technology
works (great manual!), here is what you must do;

"Locate the R8 resistor in the corner of the motherboard 
nearest the Printer Port; clip it on one end and bend
it aside to prevent contact.

DO NOT REMOVE IT, so that you can later reconfigure your
Mac Plus back to 1 MB if necessary.  If R9 is in place,
it will also need to be clipped.  It is only used if
your machine is configured as 512kb or 2MB."

SIMM Configuration

Row 1 (SIMMs 1 & 2) - 1 meg simms
Row 2 (SIMMs 3 & 4) - 256 k simms
