Memory Upgrade

Operation
You must replace the mini-touch panel's 128KB integrated circuit (IC) with a 512KB
IC to increase the storage capacity (memory) for control pages and symbols. You will
need a Phillips screwdriver and a non-conducting flat-blade tool to slip under the IC
and pry it out of its socket.
