My olde worlde Multi Depacker could also handle Power Packer files. Not that I used it to depack modules that I'd ripped out of Amiga games back in the day and transfer them as PowerPacker files to save space on the CrossDOS formatted disks at all
My main site: http://www.mug-uk.co.uk - slowly digging up the bits from my past (and re-working a few): Atari ST, Sega 8-bit (game hacks) and NDS (Music ripping guide).
I develop a free Word (for Windows) add-in that's available for Word 2007 upwards. It's a fix-it toolbox that will allow power Word users to fix document errors. You can find it at: http://www.mikestoolbox.co.uk
