╘HE ─┴╘┴ ├╚╔┼╞ IS A ├OMBINATION ╚┴╥─ ─╔╙╦ AND ╞╠╧╨╨┘ ─╔╙╦ DATA STORAGE SYSTEM FOR USE WITH THE ├64 AND ├128. ╘HE ╞OLLOWING ARTICLE DESCRIBES JUST HOW THE SYSTEM IS CONFIGURED AND HOW IT WORKS.
╚┴╥─╫┴╥┼:
╘HE ─┴╘┴ ├╚╔┼╞ IS HOUSED IN A ╨.├. STYLE FLIP TOP CABINET. ╘HIS ALLOWS THE 64 OWNER TO SET UP HIS COMPUTER SYSTEM EASILY AND COMPACTLY. ╘HE MONITOR CAN BE SET UP ON TOP, AND THE ├64 OR ├128 PLUGGED INTO THE ├HIEF THROUGH THE SERIAL CABLE. ╘HE SYSTEM IS SUPPLIED POWER VIA A 135 WATT SWITCHING POWER SUPPLY. ╘HE CABINET ALSO PROVIDES ROOM FOR FUTURE INSTALLATION OF MODULES CURRENTLY UNDER TESTING BY ╔├╘.
╘HE ─┴╘┴ ├╚╔┼╞ COMES WITH A ├-64 COMPATIBLE FLOPPY DISK DRIVE. ╘HE FLOPPY WORKS JUST LIKE THE 1541, AND THE HARD DRIVE WORKS IN TANDEM WITH THE FLOPPY. ╘HIS IS ONE REASON WHY THE HARD DISK IS SO COMPATIBLE AND TRANSPARENT TO THE C64, AS SHALL BE SEEN IN THE SYSTEM DESCRIPTION.
╘HE ╞LOPPY AND ╚ARD DRIVES ARE BOTH 1/2 HEIGHT, LEAVING TWO 1/2 HEIGHT SPACES (OR 1 FULL SPACE) FOR FUTURE DRIVE ADDITIONS. ╘HE HARD DRIVE CONTROLLER THAT IS STOCK IN THE ─┴╘┴ ├╚╔┼╞ CAN CONTROL TWO HARD DRIVES. ╙INCE THE ─┴╘┴ ├╚╔┼╞ COMES STOCK WITH ONLY ONE HARD DRIVE, THE USER CAN ADD A SECOND HARD DRIVE WHEN PURCHASED FROM ╔├╘. ┴DDING A THIRD HARD DRIVE CAN BE ACCOMPLISHED BY ADDING A SECOND PRIMARY HARD DISK CONTROLLER CARD AND THEN ADDING THE HARD DRIVE.
╙┘╙╘┼═:
╨ERHAPS THE MOST INTERESTING FEATURE OF THE ─┴╘┴ ├╚╔┼╞ IS ITS EASE OF OPERATION. ╘HE FLOPPIES ARE LOADED FROM THE FLOPPY DRIVE CONTROLLER INTO THE HARD DISK AS INDIVIDUAL DISKS. ╘HE HARD DISK OPERATES AS 60 FLOPPIES PER 10 MEGABYTES. ╘O ACCESS A PARTICULAR PROGRAM FROM THE HARD DISK, FIRST ACCESS THE FLOPPY DISK ON THE ╚ARD DISK, AND THEREAFTER TREAT THAT DISK AS IF IT WERE DEVICE 8 OR AS THE ORIGINAL FLOPPY. ╘O GET BACK TO THE FLOPPY, A COMMAND IS GIVEN TO HAND ACCESS BACK TO THE FLOPPY. ╚ERE'S AN EXAMPLE OF HOW IT WORKS.
╞IRST ASSUME THE HARD DISK NOW AS 60 DISKS LOADED INTO IT.
1. ╘O ACCESS DISK #49 FOR EXAMPLE: ╘YPE '╧╨┼╬ 15,8,15,"╚49" ╘HIS OPENED THE COMMAND CHANNEL TO HARD DISK 0 (OR THE FIRST HARD DRIVE) AND TO THE TRACK AND SECTOR OF THE FLOPPY RESIDING IN PARTITION #49.
2. ╘O READ THE DIRECTORY OF THAT DISK: ╘YPE ╠╧┴─ "$",8
3. ╘O LOAD A PROGRAM FROM THAT DISK: ╘┘╨┼ ╠╧┴─"PRG. NAME",8 (OR,8,1) AS REQ UIRED TO LOAD THAT TYPE OF PROGRAM.
4. ╙TANDARD FILE STRUCTURES ARE SUPPORTED ON THE HARD DRIVE.
5. ╘O RETURN TO THE FLOPPY DRIVE: ╘┘╨┼ ╧╨┼╬ 15,8,15,"╚0"
┴S CAN BE SEEN ABOVE, THE ╚┴╥─ ─RIVE EMULATION OF THE FLOPPY DISK IS TREATED BY THE SOFTWARE AS IF IT WERE THE DEVICE 8. ╘HIS HAS IMMENSE ADVANTAGES IN THAT IT ALLOWS MUCH BETTER COMPATIBILITY FOR SOFTWARE OPERATION (FOR EXAMPLE IN WORD PROCESSOR FILE HANDLING).
╞LOPPY DISK TRANSFER FROM FLOPPY TO ╚┴╥─ ─╥╔╓┼ IS VERY SIMPLE. ╙OFTWARE WITH ERRORED TRACKS CAN BE TRANSFERRED IN MOST CASSES, AND A NOVEL UTILITY ROUTINE ALLOWS THE COMPUTER TO TRANSFER MOST ERROR DIRECTLY TO THE HARD DISK. ╔T SHOULD BE ADDED THAT THE TECHNIQUES WORK REMARKABLY WELL AND THE SYSTEM IS VIRTUALLY TRANSPARENT IN OPERATION.
╘HE ┬╧╙-╨┴╦ IS A PLUG-IN AND RUN OPERATING SYSTEM FOR THE ─┴╘┴ ├╚╔┼╞ THAT PROVIDES QUICK EASY UPDATE OF THE HARD DRIVE OPERATING SYSTEM. ╘HE ╓┼╥╙╔╧╬-┬╧╙ 3.1 ENHANCES THE SYSTEM CAPABILITY, FLEXABILITY AND POWER FOR THE USER BY PROVIDING A ┬╧╙╙ (┬UFFERED ╧PERATING ╙YSTEM ╙WITCH), ALLOWING SELECTION OF OPERATING ═╧─┼╙ AS FOLLOWS:
═╧─┼ 0: ─╔╙┴┬╠┼╙ ═╧─┼ ╞╒╬├╘╔╧╬
═ODE 0 DISABLES THE ═╧─┼ FUNCTION AND RETURNS THE DISK INTO A PARTITIONED DRIVE.
═╧─┼ 1: ├╚┴╔╬ ┼╬┴┬╠┼/─╔╙┴┬╠┼
╔N THIS MODE, THE ┬╧╙ ╙WITCH ALLOWS THE USER TO SWITCH THE HARD DRIVE FROM STANDARD PARTITIONED MODE TO CHAIN MODE. ╔N THE CHAINED MODE, A DIRECTORY WILL GIVE WILL GIVE A LISTING OF ALL DISK CONTENTS WITHIN THE CHAIN. (╧R ALLOW ANY CONTENT TO BE LOADED REGARDLESS OF EXISTING PARTITION ADDRESSED BY THE HARD DRIVE.) ╫HEN THE HARD DRIVE FIRST BOOTS, IT IS AUTOMATICALLY ADDRESSED TO THE ╚┴╥─ ─╥╔╓┼ PARTITION #1, (╫ITH ┬╧╙╙ ╙╫╔╘├╚ IN ─╧╫╬ POSITION) WITH ALL REMAINING PARTITIONS IN THE CHAIN. ╘HE USER CAN RE-PROGRAM THE CHAIN LOCATION BY USING ═╧─┼ 4.
═╧─┼ 2: ╙╧╒╥├┼/─┼╙╘╔╬┴╘╔╧╬
╘HIS ═ODE ALLOWS THE USER TO RUN MOST COPY PROGRAMS AND USE THE SWITCH TO DESOIGNATE ╙OURCE/─ESTINATION (╞LOPPY/╚ARD DRIVE). ╞OR EXAMPLE, WHEN A FAST COPY PROGRAM INSTRUCTS THE USER TO INSERT THE SOURCE DISK AND HIT RETURN, THE SWITCH IS MOVED UP (I.E. FLOPPY) AND RETURN IS HIT. ╫HEN THE PROGRAM ASKS THE OPERATOR TO INSERT THE DESTINATION AND HIT RETURN, THE SWITCH IS MOVED DOWN TO THE HARD DRIVE POSITION AND RETURN IS HIT. (╘╚┼ ─┴╘┴ ╔╙ ╘╥┴╬╙╞┼╥╥┼─ ╞╥╧═ ╘╚┼ ╞╠╧╨╨┘ ╘╧ ╘╚┼Çú╚┴╥─ ─╥╔╓┼.)
╔N ═ODE 3, THE ┬╧╙ ╙WITCH IS FLIPPED TO THE FLOPPY POSITION, A PROTECTED PROGRAM IS BOOTED FROM THE FLOPPY DRIVE, AND ONCE BOOTED THE SWITCH IS FLIPPED TO THE HARD DRIVE POSITION. ╬OW THE PROTECTED SOFTWARE IS RUNNING AND FILE ACCESS WILL BE TRANSFERD TO THE HARD DRIVE.
═╧─┼ 4: ╔╬╔╘╔┴╠╔┌┼╙ ├╚┴╔╬ ╙┼╘-╒╨ ╨╧╙╔╘╔╧╬
═ODE 4 IS USED TO SET UP A CHAINED PARTITION AREA AS ONE DISK LOCATION. ╘HE USER SIMPLY SPECIFIES THE STARTING DISK AND ENDING DISK AS IN THE FOLLOWING EXAMPLE: ╘O SET UP A CHAIN FROM ╚89 THRU ╚110
╘┘╨┼ ╧╨┼╬ 1,8,15,"╚═4 89 110"
╘HIS EXAMPLE WOULD SET UP A PARTITIONED AREA AS ╚89 THAT WOULD BE 14,608 BLOCKS. ╔N ADDITION, MULTIPLE CHAINS CAN EXIST AND BE EXECUTED VIA PROGRAMING. ╫HEN A DIRECTORY IS REQUESTED FOR THE CHAIN, ALL "╚" PARTITIONS IN THE CHAIN WILL BE LISTED. ╫HEN THIS COMMAND IS ISSUED, IT ALSO PERFORMS THE ╚╔ COMMAND. (┴LLOCATION OF TOTAL BLOCKS ╞REE).
╔N ADDITION TO THE FUNCTIONAL VERSATILITY OF THE ┬╧╙╙ ═╧─┼╙, ╘HE ┬╧╙ ═ODULE ITSELF WILL ALLOW THE USER EASE OF UPDATING THE ─┴╘┴ ├╚╔┼╞ OPERATING SYSTEM. ╘HE MODULE SIMPLY PLUGS INTO A CONNECTOR LOCATED ON A CONTROLLER BOARD. ┴╠╠ ├╒╙╘╧═┼╥╙ ╫╔╠╠ ╥┼├┼╔╓┼ --╞╥┼┼-- ┬╧╙-╨┴╦ ╒╨─┴╘┼╙ ╞╧╥ 3 ═╧╬╘╚╙ ╞╥╧═ ─┼╠╔╓┼╥┘.
╘HE ┬╧╙ ALSO PROVIDES OTHER COMMANDS FOR EASY OPERATIONS:
