GO 64 (9)..AS ITS NAME IMPLIES, THIS WIL L SWITCH THE COMPUTER TO 64 MODE, SIMILA R TO GO64 IN BASIC. YOU WILL BE ASKED T O CONFIRM BEFORE THE ACTION IS ACTUALLY PERFORMED. HOWEVER, THE SERVANT USES A SLIGHTLY DIFFERENT APPROACH WHEN SWITCHI NG THE COMPUTER TO 64 MODE. IF YOU'RE N OT TECHNICAL MINDED, YOU CAN JUST SKIP T HE REST OF THIS EXPLANATION. YOU WILL P ROBABLY NOT BE ABLE TO DETECT THE DIFFER ENCE...IF YOU'RE A PROGRAMMER, THIS FEAT URE MAY OPEN SOME INTERESTING POSSIBILIT IES. AS YOU KNOW, THE 128 HAS TWO DISTI NCT SEGMENTS OF RAM MEMORY OF 64K EACH C ALLED BANKS. BASIC USES ONE BANK (BANK 0) TO STORE SYSTEM VARIABLES, VECTORS, P ROGRAMS AND HIGH RESOLUTION SCREENS AMON G OTHER THINGS, AND THE OTHER (BANK 1) T O STORE BASIC VARIABLES. NORMALLY, WHEN YOU ENTER GO64 IN BASIC OR RESET THE CO MPUTER WHILE HOLDING DOWN THE C= KEY, TH E COMPUTER WILL SET UP 64 MODE TO WORK I N BANK 0, AND BANK 1 WILL BE UNACCESSIBL E ENTIRELY AS LONG AS YOU STAY IN 64 MOD E. THE SERVANT HOWEVER, SETS UP 64 MODE IN BANK 1. THIS IS ALSO TRUE WITH ALL OTHER FEATURES IN THE SERVANT THAT SWITC HES THE COMPUTER TO 64 MODE...SO WHAT? WELL, USING BANK 1 DOES HAVE A QUITE SIG NIFICANT ADVANTAGE: YOU CAN RUN 64 MODE ML OR BASIC PROGRAMS AS USUAL. THEN, Y OU CAN RESET THE COMPUTER, AND EXAMINE T HE ENTIRE MEMORY FROM $0400 TO $FEFF WIT H THE MONITOR WITHOUT CORRUPTION. SCREE N MEMORY, RAM UNDER ROM & I/O WILL BE IN TACT. THEN YOU CAN USE GO 64 FROM THE M ENU TO RETURN TO 64 MODE, AGAIN WITHOUT CORRUPTION (SCREEN MEMORY WILL BE CORRUP TED OF COURSE, BECAUSE THE SCREEN IS CLE ARED IN THE PROCESS). ..I HAVE EVEN MOR E IN MY SLEEVE. HOLD DOWN SHIFT WHEN YO U SELECT GO 64, AND A BASIC PROGRAM WON' T EVEN BE NEW-ED, EVEN VARIABLES WILL BE INTACT! EVEN UTILITIES WILL STILL BE W ORKING! YEP, SEE FOR YOURSELF. THE ONL Y EXCEPTIONS ARE SOME UTILITIES WHICH DE PEND ON PRE-SET CONDITIONS IN THE I/O AR EA (SPRITES FOR EXAMPLE). YOU CAN RUN P ROGRAMS IN 128 MODE WHILE PRESERVING 64 MODE MEMORY, PROVIDED THEY DON'T CORRUPT BANK 1 MEMORY. RUNNING 128 BASIC PROGR AMS IS ALSO POSSIBLE IF YOU CHANGE THE V ARIABLE AREA. POKE48,160:CLR WILL PROTE CT THE 64 MODE BASIC AREA, LEAVING 24K F OR VARIABLES IN 128 MODE. IF YOU WISH T O PROTECT THE 49152 ($C000) AREA AS WELL , USE POKE 48,224:CLR, LEAVING NEARLY 8K OF VARIABLE SPACE. THE SECRET BEHIND T HIS SPECTACULAR FEATURE IS THAT THE LOWE ST 1K OF THE 64 MEMORY WHICH CONTAINS AL L IMPORTANT POINTERS AND VECTORS IS SAFE UNDER THE 1K COMMON AREA WHICH IS COMPL ETELY INACCESSIBLE IN 128 MODE WITHOUT T HE USE OF SOME ML TRICKERY. PLEASE NOTE THAT THE COMPUTER WILL CRASH (IF USING SHIFT/9) UNLESS YOU HAVE ALREADY BEEN IN 64 MODE AT LEAST ONCE SINCE THE COMPUTE R WAS POWERED UP. ..TO BE ABLE TO EXPLO IT THIS FEATURE YOU MUST BE CAREFUL ON H OW YOU ENTER 64 MODE: YOU SHOULD ALWAYS ENTER 64 MODE BY USING ONE OF THE SERVA NT'S FEATURES. THE SERVANT WILL ALWAYS DROP YOU INTO BANK 1. ON THE OTHER HAND , USING GO64 FROM BASIC, RESETTING THE C OMPUTER WHILE HOLDING DOWN THE C= KEY OR BOOT SOFTWARE WHICH AUTOBOOTS INTO 64 M ODE (AS MANY GAMES DO), THE COMPUTER WIL L USE BANK 0 AS PER NORMAL PRACTICE..
