- Commodore VIC 1541 Tutorial Part 2

- note: (part 1 was on LOADSTAR # 1)
-
-
- by: Joel Ellis Rea
-
-
- Last month we discussed the ances-
-
- try of the 1541 disk drive. If you
-
- missed it, check out the back issues
-
- offer.
-
- This month we will discuss the bas-
-
- ics of how the disk holds information,
-
- and how to do the four most important
-
- operations on a disk:
-
- 1. Format a NEW disk so that
-
- information can be organized
-
- on the surface of the disk.
-
- 2. SAVE a program onto the disk.
-
- 3. LOAD a program from the disk.
-
- 4. Make a BACKUP of the infor-
-
- mation from one disk to an-
-
- other in case Murphy visits!
-
-
- We will not discuss the why's and
-
- wherefore's of the particular commands
-
- and syntaxes and such this time. We
-
- will just show the commands.
-
- When you got your disk drive, you
-
- more than likely received a disk en-
-
- titled "1541 TEST/DEMO". If you have
-
- no such disk, go out and buy a copy of
-
- the "1541 Bonus Pack" disk from a lo-
-
- cal dealer. It is inexpensive and
-
- very useful!
-
- With the "1541 TEST/DEMO" disk in
-
- your drive, type:
-
- LOAD "C-64 WEDGE",8: (at this point
-
- hold down the SHIFT key and press
-
- the RUN/STOP key. DO NOT hit RE-
-
- TURN!)
-
- This will load and run DOS Manager
-
- Version 5.1, also known as the DOS
-
- Support Program or the DOS Wedge. You
-
- should load the DOS Manager (herafter
-
- called the Manager) every time you
-
- turn on your computer, except when you
-
- are just going to run a pre-packaged
-
- program like Loadstar.
-
- If you have the Disk Bonus Pack in-
-
- stead of the 1541 TEST/DEMO disk, you
-
- will have to insert it instead and
-
- type:
-
- LOAD " DOS 5.1",8,1
-
- Wait for the drive to stop and the
-
- word "READY." to appear, then type:
-
- SYS 52224
-
- That will also activate the Manager
-
- for you.
-
- The Manager makes it easier to use
-
- the disk drive. You can use the drive
-
- without it, but it is much more tedi-
-
- ous. We will not discuss non-Manager
-
- commands this time.
-
- Before you can use a new, blank
-
- disk, the disk must first be prepared
-
- for use by a 1541 drive. This prepar-
-
- ation is called "formatting". This
-
- needs to be done only once per disk
-
- unless the disk is physically erased,
-
- partially or completely. You should
-
- format all of your blank disks as soon
-
- as you get them home!
-
- To format a disk, type:
-
- @NEW0:disk name,id
-
- The "disk name" can be any name of
-
- your choice up to 16 characters long.
-
- It cannot contain a comma, colon, as-
-
- terisk, question mark or quote. The
-
- "id" is a Disk Identifier. It must be
-
- exactly two characters long, with the
-
- same restrictions on legal characters
-
- as the "disk name". WARNING! The
-
- disk "id" MUST be DIFFERENT on EVERY
-
- DISK YOU OWN!!! Some examples:
-
- @NEW0:JUNQUE DISQUE,JD
-
- @NEW0:MY LETTERS #1,L1
-
- @NEW0:ACCOUNTING 5,A5
-
- Some examples of illegal format com-
-
- mands:
-
- @NEW0MY FAVORITE,MF
- (No colon)
-
- @NEW0:"GOOFY" STUFF,GS
- (Quotes in disk name)
-
- @NEW0:LOADSTAR PROGRAMS,LP
- (Disk name too long)
-
- @NEW0:DISK #1,1
- (Id too short)
-
- @NEW0:DATA DISK
- (No id. This is legal, but the
- disk will not be formatted --
- just erased and renamed. Use
- this to re-use an already for-
- matted disk that has nothing
- on it you want to keep.)
