     [4]  ÔHE TOP AND BOTTOM HALVES OF THE COMPUTER ARE NOW HELD TOGETHER BY 
     TWO  INTERLOCKING  PLASTIC TABS.  ÔHE TWO TABS PROTRUDING DOWN FROM THE 
     TOP  HAVE  "TEETH"  POINTING  OUTWARD,  THAT INTERLOCK WITH THE BOTTOM. 
     ÔHESE  TABS  ARE  LOCATED AT A POINT BETWEEN THE TOP ROW OF NUMBER KEYS 
     AND  THE  SINGLE  ROW  OF  FUNCTION KEYS AT BOTH SIDES OF THE KEYBOARD.  
     ÐRESS THE TOP ÉÎ AT THIS SPOT, (AWAY FROM THE BASE AND TOWARDS CENTER), 
     AS  YOU  LIFT  THE TOP UP. ÙOU MAY ALSO TRY TO PULL THE BASE ÏÕÔ AT THE 
     SAME POINT. ÏNCE ONE SIDE IS FREE, THE OTHER WILL FOLLOW EASILY.
