The Macintosh SE/30 is one thing that will make the process easier if if it works well.

First thing first, try disabling extensions (basically INIT code that enhances functionality) by holding the Shift key during startup. Some security software will disappear this way. After you've done so, track down the software in the Extensions folder in the System Folder (click on the hard drive icon, then system folder, then Extensions, then find the software, drag it into the trash, and then click on Special->Empty Trash.

If that doesn't work, booting off a System disk will almost always solve the case.

I assume you have a PC with a floppy drive, right? If so, you need to stop by http://68kmacwin.googlepages.com/winmac, a very useful page made by a fellow soldier who goes by the UN benjgvps.

First things first, download the Floppy Image Writer program. I'm pretty sure this works better with an internal floppy drive, but an external one will suffice.

Then, download the PC Exchange and the Stuffit Expander 4.0.1 links in the page. THIS IS A VERY IMPORTANT STEP!

Unzip the FLW (what the image writer will now be referred to at this point), and open it up. Have a floppy disk on hand; PC floppies are A-OK.

Click Load Image

-Desktop (or wherever else the image is)

-click on the PC Exchange image

-Open

Then, stick your floppy in and press Write Image.

The following is quoted from benjgvps himself:

Now go to your mac and put the disk in, go to your hard drive and find the system folder, then go to the control panel folder, then drag the "PC Exchange" file into the folder. Now your mac can read PC formatted floppies
Open the floppy writer program on your PC and put a floppy in. Click "browse" in the "write floppy" section and find the "stuffitexpander" image. Click "Open", Then "Start", Then "Yes".

Now on your mac go to the floppy and drag the "stuffit expander 4.0.1" folder on your hard drive (Do not drag onto the desktop unless you drag it into a folder on your desktop). To use stuffit expander go into the folder and click stuffit expander, click file and then expand (or "apple key" and "E"), then find the file you want to expand.

Click to expand...
