68k emulation or Disk Doubler file expansion on Mini Core Duo

I have a somewhat esoteric question, for the die-hard mac fans.

I recently unearthed two CDs that are copies of the contents of the two hard drives I had in my Mac Quadra 660AV in college (I am dating myself). At first I was overjoyed to be able to read all my old files, but that joy turned to despair when I discovered that the files are all compressed using Disk Doubler, which was a utility for keeping all your files compressed and only uncompressing them when needed. Seems silly in the age of 400 GB hard drives.

In any case, I have been looking for a way to uncompress these files. I suspect that Norton Expand may work to uncompress them, but can't find out, because it is an OS9 app and I have a new Mac Mini core duo, which does not support classic mode. Another, preferable option would be to run the original unzipping program in emulation mode. This would require a 68k emulator that works on OSX. I found a fellow who had ported Basilisk II to OSX, but since I chucked my defunct 660AV, I don't have the ROM file and thus can't run Basilisk II.

So these are my questions:
1) Anyone know of an OSX-compatible unzipper for disk doubler?
2) Is anyone out there running Basilisk II on OSX that could connect with me to walk me through how to get it working for me?
3) Failing 1 and 2, would anyone be willing to run Norton Expand for me under Classic emulation and unzip a subset of my files? I can post the files to an FTP site, along with a copy of Norton Expand.

Many thanks!

Hi, BigDaddy33.

By the numbers:

1. Extensive Googling has come up with nothing that is native in Mac OS X. StuffIt Exapnder once opened those types of files, but other reports on the Web indicate that the function to open those was dropped some time ago.

However, here's an idea for you: try SheepShaver a project that is attempting to get Classic working on Intel-based Macs. Reviews have been so-so and I've not tried it, but it may be worth a shot.

2. Not I.

3. No friends with a PPC-based Mac with Classic installed? If the idea in point 1 fails, I'll give it a try. E-mail the particulars to me as I suspect you may not want your files scattered across the Internet.

I know one can download Norton Expand from a link to the Symantec FTP site found in this Symantec KB page.

There is also dd-expand which can be found here.

Both Norton Expand and dd-expand are Classic applications.

Good luck!

In the end and with a little help I got Basilisk II up and running, and expanded all the files myself with the DD expand tool. It was quite a trip to see my old 12 year old computer, background settings, files, programs and all, running windowed on my new computer. For those who may attempt this in the future, one key fact: when naming your Basilisk II drive, name it something that ends in .img so that you can mount it in OS X and drop files in once you have initialized it in Basilisk II.
