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 ... 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.
