- INTRODUCTION
- ------------
-
- The 3 1/2 inch, Commodore 1581 disk drive was released in 1987 as a
- 3160 block, 800K mass storage device, at nearly two-and-a half times more
- disk space than a double-sided 1571 drive. Even though you cannot use the
- 1581 drive to store copy protected programs, it is an ideal data storage
- unit for compressing word processer spell checking and thesaurus files on
- to one disk. Even larger data base programs such as the 574 Relative block
- "trans.file" used in Silva Porter's Personal Finance can now process
- information more rapidly due to much quicker data management transfer
- rates.
-
- Even though the 1581 floppy disk drive has been around since 1987, not
- a lot of support has been shown from commercial software companies, until
- The 1581 Tool Kit appeared with its set of professional utilities. It also
- provides programmers with inside information on the 1581 workings and even
- includes a diagnostic public domain program called "1581.DIAG" that was
- written by a concerned Commodore employee to detect manufacturing 1581
- problem Bugs. I ran this program on my own 1581 drive and found that a
- jumper (J1) on the main PC board had been left off in production which
- affects the 6 ms step rate. Not only will this program detect the
- improperly grounded jumpers on the 1581, but will check to see if you have
- the updated WD1772 chip which replaced the WD1770 IC's used in early
- production drives, causing corrupted disk directories.
-
-
- SYSTEM REQUIREMENTS
- -------------------
-
- The 1581 TOOL KIT operates with either a C64, SX64 or C128/128D
- computer that autoboots directly to the C64 mode. It does require that you
- use at least one 1581 drive and will also support the use of a second 1581
- Commodore drive. The 1581 Tool Kit also features fast copiers, allowing
- copying of files between a 1581 drive and either a 1541 or 1571 disk drive
- with different device numbers.
-
-
- WHAT YOU GET !!!
- ----------------
-
- The 1581 Tool Kit is composed of ten different types of disk utility
- programs from within a main menu which can be loaded up from any disk drive
- device number. The latest version (v2) upgrade has a number of
- improvements over the original program first released in 1988. These
- refinements now include: New commands added to the Single Drive Fast Data
- Copier, such as a Video RAM (64K) toggle ON/OFF for 128D or C128 computers
- equipped with the expanded video RAM. Upgrading the C128's video RAM to 64K
- requires replacing the 4416 or 4164 RAM chips with a pair of 4464
- integrated circuits. An easier method is to purchase the C-128 VIDEO RAM
- UPGRADE CAT# COO592 from Software Support International. Also included is
- a 1750 or 1764 REU ON/OFF toggle, either allowing for fewer disk swapping
- passes when copying files using only a single drive.
-
-
- FAST DATA COPIERS
- -----------------
-
- Fast data copiers are used to make fast backups of unprotected
- software. From within this option you are given the opportunity of either
- using a single drive or a dual drive copier. The single copier will take
- approximately 10 minutes with 16 disk swaps to copy a complete 3 1/2"
- diskette while the dual drive will require only about two minutes when
- using two 1581 disk drives. If however, you have a 128D or a C128 with the
- video RAM (64K) installed, only eight passes will now be required to copy
- the same 1581 diskette using the single Fast Copier program. In a like
- fashion, even fewer passes will be required if you have either a 1764 REU,
- at three passes or the 175O REU requiring only a two pass disk swap to copy
- a complete 3 1/2" diskette.
-
-
- FAST FILE COPIER
- ----------------
-
- This program is designed to transfer single files back and forth
- between 1541, 1571 or 1581 drive formats. In the two drive copier version,
- you can select from the menu which disk drive you want as your source and
- destination drive from 8, 9, 10 or even 11 device numbers. This program
- will also detect if you are using two 1581 drives by switching on the
- subdirectory routine to copy partitions between drives. The single drive
- copier will still require you to make disk swaps until the copy is
- completed. As mentioned above, the use of video RAM or a REU device can
- cut this disk swapping to a minimum however.
-
-
- DIRECTORY EDITOR
- ----------------
-
- This programming tool allows you to modify the directory of almost any
- unprotected 1581 diskette. It includes an alphabetizer, rename disk
- option, and the ability to lock or unlock files. It also lets you insert
- separators in your directory for easier readability and supports partitions
- on the 1581. You can also switch between four different device numbered
- disk drives for easy access.
-
-
- TRACK & SECTOR TRACKER
- ----------------------
-
- If you want to examine the data on your 3 1/2" diskette by their track
- and sector, then this utility module is what you're looking for. You can
- also modify sectors and print Hex/Dissemble listings too.
-
-
- FILE TRACK & SECTOR TRACKER
- ---------------------------
-
- The File Track & Sector Tracker allows you to examine, modify or
- repair a file directly from a diskette. It also gives you the option of
- seeing data in either a DISASSEMBLE MODE or a HEX/ASCII MODE format. The
- DISASSEMBLE function allows you to modify the opcode and the operand while
- the HEX/ASCII mode allows you to change the block on the file as well as
- display the complete Track and Sector grid.
-
-
- PARTITION CREATOR
- -----------------
-
- The Partition creator is just that, but much more! Trying to use the
- "OPEN" command as described in the Commodore's 1581 manual is painful and
- confusing, to say the least. That's where The 1581 Toolkit comes in, to
- open, close, create and even delete partitions with ease. This module has
- a section that will display all 80 tracks on your 3 1/2" diskette and
- allows you to jump from partition to partition for quicker viewing.
-
-
- FAST FORMATTER
- --------------
-
- When you select this mode you can now format 1581 diskettes about 30%
- faster than normal. You also have the option to perform custom or partial
- formatting by selecting the beginning and ending tracks to be formatted on
- a diskette.
-
-
- ERROR SCANNER
- -------------
-
- The Error Scanner can be used to detect whether or not a disk has any
- DOS errors. In this portion of the program a visual representation of the
- integrity as well as the entire data usage can be displayed or even printed
- out.
-
-
- RE-LOCATABLE FAST LOADER
- ------------------------
-
- If you have Jiffy DOS or a fast load utility cartridge you know how
- much quicker files can be loaded and saved. Even though the Commodore 1581
- access time is faster than a 1571 drive, this fast loader module has
- several advantages over stock 1581 disk drives. Implementing the RE-
- LOCATABLE FAST LOADER and the 1581 drive can now load files up to 900%
- faster, it will relocate into memory and this file can be saved for
- convenient autobooting on a particular diskette.
-
-
- "What More Could You Expect ?"
- ------------------------------
-
- With all these menu driven utilities and a descriptive spiral bound
- manual what more could you expect from a software package? Well, also
- packaged in the manual is another 147 pages in book form called "The 1581
- DOS Reference Guide" describing the inside workings of the 1581 operating
- system including things that the COMMODORE 1581 user's guide forgot to tell
- you about.
-
-
- CONCLUSION
- ----------
-
- Even with all the great features of The 1581 Tool Kit, it does have a
- few shortcomings. The first is the fact that this program will only run in
- the C64 mode and will not fully utilize all of the Commodore 128 mode's
- enhanced features. In addition, two of The 1581 Tool Kit modules, Fast
- Formatter and the Error Scanner may not always function properly. This is
- due to the fact that the 1581 drives were originally built for European
- consumption according to the technical department at Software Support
- International and there are no future plans to upgrade this software by
- fixing these problems.
