SHRINKIT for the APPLE II+ and non-enhanced IIe
Shrink and UnShrink are separate programs by Andy Nicholas which
let 64k Apple II users create and access ShrinkIt archives.
Files ...
SHRINK.SYS -- SHRINK for II+/IIe version 2.1, Length: 11472 bytes
UNSHRINK.SYS -- UNSHRINK for II+/IIe version 2.1, Length: 12511 bytes
The files are not in compressed form.
Equipment required to use the programs ...
At least a II+ or IIe with two 5.25" drives
Using the Programs
First, SHRINK.SYS and UNSHRINK.SYS should be placed on a
bootable ProDOS diskette which also has BASIC.SYSTEM. The files
have no special headers; so, they may arrive as type Text or type
Bin files. (You can tell by doing a CAT of the disk on which the
files are located.) Use a filetype changer to change the filetype
of each to SYS (which is type number $FF).
An alternative way to change the filetype is to boot ProDOS
and, then BLOAD each file and BSAVE it as type SYS.
For example, suppose a CAT shows SHRINK.SYS and UNSHRINK.SYS
are TXT type files. You would ...
BLOAD SHRINK.SYS,TTXT,A$2000
DELETE SHRINK.SYS
CREATE SHRINK.SYS,TSYS
BSAVE SHRINK.SYS,TSYS,A$2000,L11472
and
BLOAD UNSHRINK.SYS,T$TXT,A$2000
DELETE UNSHRINK.SYS
CREATE UNSHRINK.SYS,TSYS
BSAVE UNSHRINK.SYS,T$SYS,A$2000,L12511
To start either program you can use the "-" command.
For example, at the BASIC prompt, you could enter ...
-SHRINK.SYS
to run SHRINK.SYS.
Example A: Using SHRINK.SYS to create a Disk archive (a Shrinked Disk file)
1. Format a diskette for ProDOS. (You can use Copy II Plus v7.1-v8.3 or
some other utility to do the format. Or, you can copy a ProDOS diskette
and delete all of the files on the copy.) The diskette can be named
anything you like-- "Target", for example, so long as it follows normal
ProDOS naming rules. It should have no files on it. This will be the
Target diskette for the Shrinked Disk file.
2. Boot the ProDOS diskette on which Shrink is located and start
SHRINK.SYS.
3. Put the DOS 3.3 or ProDOS disk you want to shrink into Drive 1. Put
your empty ProDOS target disk in Drive 2.
4. Select "SHRINK"
5. Select "DISK"
6. Select the disk to shrink (the one in Slot 6, Drive 1)
7. Select the target disk: Press RETURN until you get to a 'window'
showing the name of your target disk in the upper left corner of the
window. (Should be disk in Slot 6, Drive 2.)
8. Type in the name of Disk archive file. For example, if the source
disk is a bunch of DOS 3.3 utilities, you might type in DOS33UTILS.SDK.
The ".SDK" is optional. It is a handy way to indicate that the file is a
whole-disk ShrinkIt archive. (Remember, total name length can not be
more than 15 characters.)
9. The program should begin to create the Shrinked disk file on the
target disk. Total time on a 1MHz II+ or IIe should be about 2.5
minutes. If all goes well, the program will BEEP when done and display
"FINISHED".
Note-1: When finished with a session of creating .SDK files, it's a good
idea to use a ProDOS version of Copy II Plus (e.g. v8.3) to VERIFY--FILE
for each archive file you have created. If an error is detected in a
file, try creating it again using a different target diskette.
Note-2: A typical .SDK file will take up most of a 5.25" disk side. If
the stuff you want to archive is on a ProDOS disk, you can save space by
selecting "FILES" in Step 5 and selecting individual files as part of
Step 6. A File archive's name usually ends in ".SHK".
Example B: Using UNSHRINK.SYS to create a Disk from a Shrinked Disk file
1. Have a 'blank' diskette ready to serve as the disk which will be
created. Actually, it does not matter whether or not it is formatted or
if anything is on it.
2. Boot the ProDOS diskette on which UnShrink is located and start
UNSHRINK.SYS.
3. Put the ProDOS disk on which the Shrinked disk file is located into
Drive 1. Put your blank disk in Drive 2.
4. Select "UNSHRINK"
5. Use Arrow keys to highlight the disk with the Shrinked disk file (the
one in Slot 6, Drive 1) and press RETURN to select it.
6. Use Arrow keys to highlight the Shrinked disk file to unshrink and
press RETURN to select it.
7. Press RETURN to accept the next display
8. At the "UNSHRINK TO" display, select the blank disk (the one in Slot
6, Drive 2).
9. The program will first format the blank disk and, then, unShrink the
Shrinked disk file to the diskette in Slot 6, Drive 2. Total time on a
1MHz II+ or IIe should be about 1.5 minutes. If all goes well, the
program will BEEP when done and display "FINISHED".
Note: If you are unShrinking a File archive (i.e. an .SHK file instead
of a whole-disk .SDK file) the diskette in Drive 2 must be formatted for
ProDOS and have enough space for the files you unShrink from the
archive.
