Getting .dsk Disk Image files from a PC to a 64k Apple II


I. Creating a 288-block ProDOS Diskette

Normally, a ProDOS 5.25" diskette has 35 tracks at 8 blocks per track for a
total of 280 blocks, with 273 blocks available after formatting. Disk image
(.dsk) files typically require 283 blocks.

In order to get the blocks needed to hold a .dsk image file on a 5.25" diskette
which can be accessed on a standard Disk ][ drive, you need to ...

1- change FILER or some other ProDOS formatting utility so that it will format
36 tracks

2- edit a couple sectors on the 36-track disk to free up a few extra sectors.


The reason for the 36-track limit is that many Disk ][ drives can not handle
more than 36 tracks. Step 2 is necessary because formatting will use up all but
1 block on track 0, which would leave you with 281 free blocks-- 2 short of the
required 283.

The PDOS288 disk has a FILER program modified to format 36 tracks and allocate
288 blocks. There is, also, a ProDOS (v1.9) modified to handle up to 288-block
5.25" diskettes. (The basic directions-- for 40-track disks-- come from Beneath
Apple ProDOS with some updating from Ross Holmes in Computist #76.)


Running the FILER program and doing a format will get you a 288-block 5.25"
diskette with 281 free blocks. To free up more blocks, use the Copy II Plus
Sector Editor to modify two sectors:

Track 0, Sector $03: Change the first byte (Byte $00) from $01 to $1D and save
the changed sector. (This deallocates Blocks 3, 4 , 5.)

Track 0, Sector $0B: Change the fourth byte (Byte $03) from $03 to $00 and save
the changed sector. (This tells ProDOS not to look for or try to use any further
root directory blocks.)

The resulting diskette will have 288 blocks with 284 free blocks-- one more than
is required for holding a .dsk file!

You can use a 36-track disk copy utility-- such as later versions of Disk
Muncher-- to make duplicates of the 288-block diskette.



II. Using the 288-block Diskette for .dsk file transfers.

With a standard NULL modem connection and a telecom utility which runs under
ProDOS 8, you can transfer a .dsk file from PC to your 288-block diskette so
long as the ProDOS 8 you boot and run under is the one on this disk (or one like
it).

The .dsk file can be transformed to disk form using DSK2FILE v3.0 (also on this
disk).  DSK2FILE v3.0 can run on a 64k Apple II+. As above, you need to be
running under the ProDOS 8 on this disk. (Note: the target diskette must be
formatted; and, you should pick the correct 'ordering' from the DSK2FILE memu--
usually, this will be DOS 3.3 ordering.)



III. Another Way

A different approach is to use Nulib (e.g. v3.24) on the PC to compress a 5.25"
.dsk image file into a .shk file. This file can be NULL modemmed to your Apple
II with no need for a special diskette or ProDOS because it will fit on a
regular 5.25" ProDOS diskette.

Once transferred, the .shk file can be unshrinked (using the version of ShrinkIt
selectable from the disk startup menu)  to a 288-block disk.  Using DSK2FILE, it
can then be transformed into diskette form as discussed above. ShrinkIt and
DSK2FILE need to run under the 288-block ProDOS on this disk.
