Whilst browsing through the hundreds of disks sent to me by Xerud/Automation (of Mega-Depacker / Unpack fame). I stumbled across a disk marked Pack-Ice.
Nothing unusual there, however on closer inspection I found it to contain the packer source! I'm sure after 20 years Axe won't mind its release! Also there's a sneak preview of how Pack Ice v3 would have looked.
