1 MEMORY POWER Switch : This switch is used to prevent discharge of the internal
Nickel-Cadmium battery, which is used for RAM back-up. The Tandy 102 will operate only
when the power switch is set to ON. Set this switch to the OFF position when the Tandy 102 will
not be used for a long period of time. Note that the RAM will not be backed up when this switch
is set to the OFF position.
2 Optional ROM and RAM Compartment : An optional/extra ROM and RAM can be inserted into
this compartment to enhance the Tandy 102 capabilities.
3 Battery Compartment : When not connected to an AC power source, the Tandy 102 gets its
power from four AA size batteries that must be installed in this compartment.
