All you need to do is pop in the 4 1MB SIMMS and cut ot the '256K' resistor. You do not need to install a resistor in the 'one' position. This will give you 4 MB of main memory. The 128K ROM's can handle 4 megs with no problems. The only real 'problem' is the cost of those SIMMS! (~$1500/4 megs). -- Lawrence A. Dziegielewski | E.I.
