APPENDIX C: THE SERVANT MEMORY USAGE..T HIS IS AN OVERVIEW OF HOW THE SERVANT US ES THE C128 MEMORY. THIS MAY SERVE AS A HELP TO AVOID CONFLICTS WITH OTHER APPL ICATIONS OR TO UNDERSTAND WHY CONFLICTS MIGHT OCCUR...WHEN YOU DON'T ACTUALLY SE E THE SERVANT ON SCREEN, YOUR COMPUTER I S COMPLETELY "STOCK", EXCEPT FOR COLORS & FUNCTION KEYS. THE SERVANT DOES NOT H OOK INTO YOUR COMPUTER'S OPERATING SYSTE M IN ANY WAY WHATSOEVER, UNLIKE CARTRIDG ES FOR EXAMPLE. THIS IS THE KEY TO THE SERVANT HIGH LEVEL OF COMPATIBILITY. TH E TRADE OFF IS THE LACK OF SOME FEATURES LIKE A FAST LOADER, DOS WEDGE AND ADDIT IONAL BASIC COMMANDS...ZERO PAGE:.THE ZE RO PAGE IS USED HEAVILY, BUT ON A NON-IN TERFERENCE BASIS. THAT IS, THE SERVANT USES LOCATIONS WHICH ARE NORMALLY CHANGE D BY BASIC UNDER NORMAL CIRCUMSTANCES. UTILITIES OR "WEDGES" SHOULD NOT SUFFER UNDER THE SERVANTS USE OF THE ZERO PAGE. ONE EXCEPTION HOWEVER, IS THE DATAMAKE R. SINCE THIS UTILITY UTILIZES THE BASI C SCREEN EDITOR, IT HAS TO USE SOME MEMO RY LOCATIONS NOT USED BY BASIC. MOST NO TABLY THIS APPLIES TO LOCATIONS 251 THRO UGH 255 ($FB - $FF)...STACK:.THE SERVANT ASSUMES THE USE OF THE UPPER HALF OF TH E STACK. THIS MEANS THAT ADDRESSES 384 TO 507 ($0180 - $01FB) IS USED. MEMORY CONFLICTS ARE AVOIDED BECAUSE THE SERVAN T RESETS THE STACK POINTER WHENEVER IT I S INVOKED...INPUT BUFFER:.THE INPUT BUFF ER AT 512 TO 672 ($0200 - $02A0) IS USED HEAVILY FOR VARIOUS STORAGE. SINCE THI S AREA IS USED BY BASIC AS INPUT BUFFER, AND THEREBY FREQUENTLY CORRUPTED, NO CO NFLICTS SHOULD OCCUR. AGAIN THE MEMORY IS USED TEMPORARILY ON A NON-INTERFERENC E BASIS...VECTORS:.THE SERVANT CHANGES N O POINTERS OR VECTORS EXCEPT ONE. THE K EYCHK VECTOR (828/$033C) IS CHANGED TEMP ORARILY TO DISABLE THE FUNCTION KEYS. B UT IT IS GRACEFULLY SET BACK TO IT'S ORI GINAL VALUE BEFORE THE SERVANT IS EXITED ...BASIC RUNTIME STACK:.BASIC RESERVES A 512 BYTE AREA IN THE RANGE 2048 TO 2559 ($0800 - $09FF) AS A STACK TO PROCESS C OMMANDS LIKE FOR-NEXT, DO-LOOP, GOSUB ET C. IN THE DISK TOOLS SECTION, THE SERVA NT USES THIS AREA AS TWO BUFFERS. THE F IRST 256 BYTES IS USED AS A GENERAL PURP OSE WORKING BUFFER, WHILE THE UPPER 512 BYTES IS USED TO HOLD THE DIRECTORY PATH FOR 1581 DISK DRIVES. THE DIRECTORY PA TH IS USED WHEN USING THE FILE COPIER WI TH ONE AND THE SAME 1581 DISK DRIVE. SI NCE THIS AREA IS NORMALLY USED BY BASIC, NO CONFLICTS SHOULD OCCUR...APPLICATION PROGRAM AREA AND BASIC PROGRAM AREA (BA NK 0):.THE DISK COPIER AND FILE COPIER U SE THE ENTIRE BANK 0 FROM 4864 ($1300) AND UP AS PART OF ITS MAIN DATA BUFFER. OTHERWISE THE SERVANT DON'T TOUCH THIS AREA. THE EXCEPTIONS FROM THIS RULE ARE OBVIOUS: IF YOU LOAD A BASIC PROGRAM F OR EXAMPLE, IT WILL OF COURSE REPLACE AN Y BASIC PROGRAM WHICH HAPPENED TO BE IN THE MEMORY ALREADY. IMPORTANT NOTE: WH EN THE SERVANT IS WORKING IN BANK 0 RAM, BANK 0 MEMORY WILL ALSO BE USED BY THE DISK TOOLS FOR STORING DIRECTORIES (SEE BELOW)...BASIC VARIABLE STORAGE AREA (BA NK 1):.ALL DISK TOOLS SECTIONS WHICH USE S A DIRECTORY, USE BANK 1 MEMORY FROM 1 6384 ($4000) AND UP TO 32768 ($8000) ACC ORDING TO THE DIRECTORY SIZE. THE FILE COPIER AND DISK COPIER USES THE ENTIRE B ANK 1 AS BUFFER SPACE. IT IS NOT POSSIB LE TO PROTECT MEMORY FROM BEING OVERWRIT TEN BY THE SERVANT...BANK 0/1 COMMON MEM ORY:.THE 128 HARDWARE HAS A PROVISION FO R RESERVING A MEMORY AREA COMMON TO BANK 0 AND 1 AT THE TOP, BOTTOM OR IN BOTH E NDS OF THE MEMORY RANGE. UNDER NORMAL O PERATION, THE 128 IS SET UP USING A 1K C OMMON MEMORY AREA AT THE BOTTOM OF MEMOR Y. THE DISK TOOLS SECTION TEMPORARILY E XTENDS THE BOTTOM COMMON AREA TO 16K TO RETAIN COMPATIBILITY WITH RAMDOS. THE C OMMON AREA IS SET BACK TO 1K UPON EXIT.. .VDC MEMORY:.IF YOUR 128 IS EQUIPPED WIT H 64K MEMORY FOR THE 80 COLUMN CHIP, THE ENTIRE MEMORY SPACE IS USED BY THE DISK COPIER AND FILE COPIER. ONLY THE AREA USED FOR SCREEN DISPLAY, ATTRIBUTE MEMOR Y, AND THE LOWERCASE CHARACTER DEFINITIO NS ARE UNUSED TO RETAIN THE SCREEN DISPL AY EVEN IF THE 80 COLUMN SCREEN IS ACTIV E. THIS WAY, THE SERVANT CAN SQUEEZE 56 K OUT OF THE VDC MEMORY. BECAUSE THE UP PERCASE/GRAPHICS CHARACTERS ARE OVERWRIT TEN, THE ROM CHARACTER DEFINITIONS ARE C OPIED BACK TO THE 80 COLUMN MEMORY UPON EXIT...RAM EXPANSION UNIT:.THE DISK COPI ER AND FILE COPIER CAN MAKE USE OF ANY S IZE REU. PLEASE NOTE HOWEVER, THE SERVA NT WON'T IDENTIFY ANY REU TO BE BIGGER T HAN 1MB, EVEN IF YOUR REU DOES HAVE MORE MEMORY ONBOARD. SINCE DUPLICATING 1581 DISKS IS THE MOST MEMORY HUNGRY JOB YOU 'RE EVER GOING TO DO WITHIN THE SERVANT, THIS LIMITATION WON'T HAMPER YOU. ALSO , USING THE REU IS PURELY OPTIONAL; THER E'S NO NEED TO CORRUPT THE REU'S CONTENT S IF YOU DON'T WANT TO..
