Using Downloaded Software

Using Software Downloaded from A2OL

The software files made available here are what are known as "disk image" files.  .DSK files are akin to backup files - that is, the entire disk is read and then saved as a single "image" file.   In order to use the .DSK file on your Apple II, you need to reconstitute the disk by using a program such as DiskMaker8 (available here) to read the .DSK disk image file and write it back to a floppy disk.  The resulting floppy disk is then useable by your Apple II.

As a means for transferring the .DSK image file, it is encased into a ZIP file for storage on A2OL and transfer to your PC.

The steps you need to take to use the software are:

  • Download the ZIP file containing the Apple II disk image to your PC
  • UnZIP the download to get to the .DSK image file
  • Connect your II to your PC using a serial cable
  • Use ADTPro (available here) to transfer the .DSK file to your Apple II
  • Use DiskMaker8 (available here) to read the .DSK file and write it to a floppy disk
  • The resulting floppy disk is then bootable/useable by your Apple II

There is an link to an excellent video on using ADTPro made by the author of ADTPro that I suggest you take a look at.  This video shows you how to connect your Apple II to a PC using a serial cable and how to bootstrap the Apple II using ADTPro. If you need a serial cable, you might be able to pick one up online. 

Cables are sometimes difficult to find for the IIc and IIGS since both have non-industry-standard serial connectors.  You can find cables for the IIGS here and for the IIc here


If you are going to be doing a lot of this sort of thing, you might also consider purchasing a MicroDrive or CFFA 3000, both of which are Apple II cards which use a CompactFlash memory card as a hard drive. You can read/write files from/to the CF card on your PC using CiderPress (available on A2OL), then simply take the CF card over to your Apple II, insert it & boot your system, and you have access to the files. This is actually what I do with my MicroDrive, & it makes life so much easier!

The MicroDrive has the advantage for Apple IIGS users using GSOS in that you can partition CF cards for volumes greater than 32 MB; the CFFA3000 card has the 32 MB limitation.

The CFFA3000 card has the advantage that you can use .DSK image files directly without the need for converting them back to physical floppy drives.  The CFFA3000 also allows you to use a USB "thumb drive" as well as a CF card.  The MicroDrive does not have the USB capabilities nor the ability to use .DSK files directly.

I have both cards and both work exceptionally well!  The only downside is that since they are internal cards, neither may be used on an IIc/IIc Plus.
